What is Mastodon? “How do I use Mastodon”
Mastodon is a micro-blogging platform. Think of Mastodon as a train station with many different trains. Each train has its own leader and its own aims and rules. Each train contains different groups of people who can write short posts, follow each other, email each other, and boost each other within their own train or across trains. You may ask “how do I use Mastodon?”
Think of “Mastodon” as a tool or a method for creating these networks. “Mastodon” is really made up of thousands of independent social networks called “instances.” A train station is a way for trains to arrive and depart.
Mastodon is open-source software (available for anyone to use) that is a way for people to “arrive” at their registered “instance” or group and to depart it.

Medium embraces Mastodon
On January 12, 2023, Medium officially posted about creating a group or an instance of Medium members using Mastodon. Medium readers and writers have to be paying members of Medium to join the Medium “instance” or group or network on Mastodon. Below is a link to the public post in Medium’s “3 Min Read” blog.
https://blog.medium.com/medium-embraces-mastodon-19dcb873eb11
Why is Medium doing this? One reason as in the post above is to “deepen people’s understanding of the world by helping to share the best ideas and best information and to help find and recommend interesting accounts.”
This sharing using Mastodon is based upon short-form posts of a maximum of 500 characters.
You can think of Medium on Mastodon as a Medium group or a Medium instance or a Medium community on Mastodon.
Important points about working with Mastodon
Posts are public by default
It’s really important to be aware that by default your posts and replies / comments to posts on Mastodon are public, meaning anyone who finds them can read them.
This means that you should never have strong identifying personal information in any of your posts or comments using Mastodon, UNLESS you “lock” or restrict your Post or Reply to your FOLLOWERS and you are okay with ALL of your Followers in the Mastodon “fediverse” seeing that information.
So don’t post your address or your bank account details, because anyone can search for an “instance” using Mastodon and if they find it, they can scroll through the Local timeline and read the posts!
The following webpage shows Mastodon instances (also referred to as “servers”) that are OPEN to new members. Scroll down the page and click on “Find a server” if you are curious about what’s open.
Note that the directory lets you search by countries and topics only. Plus, a short description about the “instance” and a “button” to create an account or join the “instance” is provided.
BUT you cannot navigate to any of the content, i.e., pages of the Mastodon instance from the Directory page. Click on “Find a server” on the page below to go to the Directory page.
If you want to look at the content, i.e., the posts in the Local timeline or feed of a Mastodon group, instructions follow.
Finding a Mastodon instance or server’s Local feed (“home page”)
Why would you want to find a Mastodon group or “server?” You join one instance which best suits your interests.
From that instance you can interact with members of the group (or “instance”) and with the “federated” members. This means Mastodon members or users can search for public content via hashtags and keywords across all open groups and interact with posts and post authors outside of one’s Mastodon instance.
Mastodon users or members, when signed into Mastodon, can find posts and people to interact with via the Explore (search) function of Mastodon and the Local timeline and Federated timeline. These search methods will be discussed later in this article.
You can go to the Local timeline of a Mastodon “instance” and browse the posts to find writers that you would like to follow. Once you find an instance’s Local timeline you should BOOKMARK it on your computer (because you can’t follow Local pages other than your own, via Mastodon), for easy access and use.
The directory above, at the time of writing this, shows “tiles” or images with the name of the Mastodon instance being the phrase with a dot between two words.

You can COPY the name of a Mastodon instance, e.g., mastodon.social and type in https:// into the browser address of your desktop computer, then paste in the name of the instance, as demonstrated below.
Then click on “Local” (or Live Feeds) which brings up the Local timeline showing public posts written by members of that instance.
There’s really no “home page” per se of a Mastodon server/instance/group. However, the LOCAL feed is where you can see the public posts by members of that “instance.”
You can see for yourself that you don’t have to be signed into a Mastodon instance in order to read the PUBLIC posts.
But to write and publish your own posts and to like and reply or comment upon others posts in your “instance” and to follow and interact with people in other “instances”, you need to sign up or register with a Mastodon “instance” and be signed into your “account.”
You won’t find Medium’s “instance” or group, called me.dm in the Mastodon directory (previously given) because it is NOT open to everyone.
Only “instances” or Mastodon communities or groups that are allowing people to apply to join them are in the directory.
Having said that, here is the link to Medium on Mastodon, which Medium has officially provided in their “3 Min Read” blog (link previously given). The web address or URL below has /public/local at the end, as it is the direct link to the Local page or timeline.
What are Servers?
It has been mentioned that a list of Mastodon servers is available by clicking on “Find a server” on the following page: https://joinmastodon.org
A server is a type of computer that receives, stores, and sends data to clients (laptops, phones, tablets). A Mastodon server “serves” information and programming applications to a defined group or “instance” of users (i.e., people using the server’s functions).
Mastodon is a micro-blogging platform made up of thousands of independent social networks called “instances.”
An instance is an instance of the Mastodon network. An “instance” is defined as an independent server hosting its own community, with its own rules, goals, and moderation.
A “server” is the infrastructure that runs an instance of the Mastodon software.
In the Mastodon world, instance and server are interchangeable meaning they both refer to the same thing.
The server or instance hosts its own community, with its own rules, goals, and moderation.

What is the Fediverse?
Mastodon is also referred to as a decentralized, distributed, “federated” social network system.
Decentralized means not controlled by one person or organization.
Distributed means it is not confined to one location. The Mastodon world of “instances” or independent “communities” aka groups or social networks is spread out within countries and locations and over multiple countries. For example, Medium’s Mastodon instance, called me.dm has members based in various countries.
Federated means the “instances” are connected to each other when any users in any one of the instances follow users in one or more of the other instances.
The Fediverse is a collection of thousands of independent social media servers that “talk” to each other seamlessly. This means that the millions of users on these servers can interact with each other as if they were on a single social network.

How do I set myself up on Me.dm (Medium’s instance on Mastodon)?
You need to be a paying (Premium) member of Medium in order to post and comment in the Medium instance or group on Mastodon.
This will allow you to follow some people in other instances/groups on Mastodon and to like and reply to posts by people in other instances/groups, when those people (or users) allow you to do so.
If you are a paying member of Medium, you can create a Mastodon account via Medium (i.e., join the Medium instance on Mastodon) by dropping down the Function Menu via clicking on your Avatar at the top right of the screen when you are signed into Medium.
Note that in the example below, the Avatar (round picture representing the Medium member) has been ERASED from the picture, for privacy reasons.
Click on “Create a Mastodon account.”

If you need to, go to Settings (via the menu that drops down from your Avatar at top right) on Medium, then click on Notifications and check the radio buttons next to the options under “Others from Medium” to receive FUTURE important emails from Medium.
If you are NEW to Medium and become a paying member, you will get the option to sign up with Medium on Mastodon when you SIGN UP AS A PAYING MEMBER.
To create your Mastodon account with me.dm (Medium on Mastodon), click on the link in your email, such as “create your me.dm account here” OR go to “Create a Mastodon account” under your Avatar when signed into Medium.
Your Mastodon address will automatically be generated based upon your Medium User Name.
On Medium, you have a Display Name and a User Name.
The User Name or username is part of the web-address or URL for your Medium Profile page. For example, my Medium User Name is CelineL and my Display Name was my everyday name before I changed it to a pen name, being Grace Mary Power 😛.
A User Name is the unique name you use to sign into an “account” where a User Name has to be input to access (or sign into) the “account.” An “account” is a gateway between yourself and an online “application” or program that is running.

Note: your Mastodon address will reflect your Medium details. The part after the second ampersand @ is the name of the Mastodon instance that you are a part of. The part after the first ampersand @ is your User Name on Mastodon.
In this case me.dm (a play upon the sound “Me-dium”) is the NAME of Medium’s instance using Mastodon.
My Mastodon address is: @[email protected]
CelineL is my Mastodon User Name (username).
A User Name is used to reply to, mention, or message individual users (or people) on the federated Mastodon network, where permissions are set by those people to allow this.
Tip: If someone in the Fediverse gives you their address, you can paste it into the Search field at top left when signed into Mastodon. Then press Return or Enter and the person’s profile name will appear in the search results, which you can click on to go to their Profile page.
Create your password and accept the rules.

The rules can be found at the link below. Read them carefully before you click ACCEPT.
This article is a beginner’s guide on using Mastodon. If you are signing up with an “instance” or group other than Me.dm, you will see similar screens during the sign-up process (i.e., terms to accept and a data entry form for your Display Name, Username, and Password).
After you successfully register, you will get a screen telling you that you are in.

Click on “Let’s Go” and then — — let’s go!
Navigating around Mastodon
Timelines
Home: a feed or stream of posts on Mastodon of people you are following. By default, this includes posts that are “boosted” by people you are following and replies or comments by yourself and people you are following.
However, you have the option of turning off the showing of “boosts” or “replies.” To do this, click on the little lines at the top right of your Home feed, in this instance, next to “Medium” — see picture below.

This will show the following.

A tick means the function is turned on and a cross means the function is turned off. Click on the round white area next to your choice to “toggle” show or not show. Click on the lines again to hide the information panel.
Local: a feed or stream of posts on Mastodon of people in your Mastodon community or instance.
Federated: a feed or stream of posts and replies on Mastodon by people in your instance and in other Mastodon instances (or groups) that are connected to people in your instance.
The connections are made when you or someone in your “instance” follows someone in another Mastodon “instance.”

What Mastodon group or instance do people belong to?
You may ask “how do I know what instance/group/server that the people whose posts and replies appear in the Federated timeline are from?”
The answer is that the part after the second ampersand @ tells you.
For example, looking at the screenshot above, Screenshot 10, the Mastodon instance name or “server name” that Barbara Dees is a member of is Activism Openworlds Info, with her Mastodon profile address below.
You can type https:// into your web browser address field and then copy and paste or type in the Mastodon instance name to go to the Explore or About page of the instance.
https://activism.openworlds.info
If there is no second ampersand @, it means that the person is a member of the Mastodon instance that you’re a member of.
Only the person’s User Name appears, for example, @ CelineL appears in the feeds or timelines of the instance that you and I are both a member of.
In other words, you will only see the User Names in the Local feed of the instance that you are a member of. The @ me.dm part is not shown because they are in that “instance.”
You will know what instance you are signed into or are viewing because either the logo or the name of it will appear at the top of the screen OR when you go to the Local timeline of an instance that you’re not a member of, you will see a banner at the top. It will be a message “These are the most recent public posts from people whose accounts are hosted by [ instance name ].”
Boosting and Following on Mastodon
Boost
Boosting means anyone can BOOST a post or a reply/comment so that it will immediately appear in the Home feed of their followers. If you don’t have any followers outside of your instance, you shouldn’t really boost posts published in your own instance (at least not the same day as the publication date of the post you want to boost).
This is because the members of your instance can see posts in the Local timeline as they are posted. Speaking for myself, I can find useful or interesting posts in my Local feed myself.
Fortunately, one can hide the boosted posts on their Home feed.
Boosting is an endorsement akin to a re-tweet on Twitter.
Be sparing with boosting because users may see the same post twice within a short timeframe, once in the Local feed and once in their Home feed, and some of your followers may not care about the content that you boost!
I recommend waiting for 12 hours at least before boosting a post that has been published in your own instance because it may be annoying to someone to read a post in their Local timeline and then go to their Home timeline (which is like a Facebook profile’s news feed showing posts of people you are following) to see the exact same post.
Boost a post by clicking on the second (2nd) icon from the left beneath a post. It looks like a “recycling” symbol.

You can hide boosts from your Home feed or timeline. See instructions under “Timelines — Home” above.
Following and blocking on Mastodon
Click on a person’s name for someone in your Mastodon instance to go to her or his Profile page.
You can attempt to follow a person by going to their profile page then clicking on Follow. The person may have “Require follow requests” enabled, meaning that requests to follow must be authorized by the person you want to follow.
If a Mastodon user’s Profile page has a padlock picture on it, it means that they have got “require follow requests” turned on.
You will know that following has to be authorized because a small notice or alert pops up after you click on “Follow”, saying “Approval waiting”. And when you go to the person’s profile page you will see a green “button” to withdraw your follow request if you want to.
There is information about how to see your list of Followers and about moderating Followers later in this article, under the heading “Viewing and moderating followers.”
Unfollow someone by going to “Preferences” in the list of menu options at the right side (under the word Medium) and clicking on “Follows and Followers”, then tick or check the box next to the person you want to stop following. Then click on “Unfollow selected users” then click on OK.
You can also go to the Federated timeline and follow a person outside of your instance. Click on the person’s name to go to their profile page and click on Follow.
Remember that the Federated timeline consists of posts and replies by people in your group or instance and by people who you and others in your instance follow!
You can mute or block someone by going to their profile page and clicking on the 3 little dots. MUTE means you won’t see their posts or replies in the Timelines, and BLOCKING means in addition to this that they won’t see your posts or replies in the Timelines.
You can also use “Block Domain” which blocks everyone who is on the same instance as the person you are blocking.
Writing posts and replies
Posting visibility
A text post on Mastodon is called a “toot”. These posts or “toots” can be up to 500 characters in length. A posting box appears at the top left when you are signed into a Mastodon instance.
Check your post’s or reply’s visibility, as described below. Type your post into the posting box. Then click on Publish.
Use a hashtag to facilitate finding or discovery of your post within and outside of your instance, if you want more discoverability.
To reply to a post, click on the left-ward pointing curving arrow, first icon on the left beneath a post.

The post will pop up on the left with a posting box below it for your reply. The posting box will automatically have @ followed by the name of the post writer in it. This “mention” or “alert” using the ampersand @ will notify the post writer of your reply.

Check your reply’s visibility, as described below.
Note that a Reply is treated as a “post” for visibility purposes.
Posts are public by default
By default, your posts and replies/comments are all PUBLIC.
This means that, as well as people in your Mastodon instance/group, even someone not registered with a Mastodon instance and someone who is, but is not logged in to their Mastodon instance, who comes across your post or reply, will be able to read it.
You can make all of your posts and replies visible only to your followers by default OR you can change the setting for individual posts and replies.
Click on the link below for instructions on changing the global setting for all of your posts and replies regarding visibility. Make sure you click on “Save changes” if you make a change.
A global setting means one setting for every post and reply that you make on Mastodon, by default.
It is a good idea to get into the habit of checking the visibility of each “post” that you create, keeping in mind that in Mastodon language, a “post” is a text field, so it is a Post OR a Reply.
How to change post visibility
When creating a Post OR a Reply, click on the third icon from the left at the bottom of the posting area and change the default post visibility just for that Post.
In this example, the visibility can be changed to Public by clicking on “Public.” The visibility options are listed below the following picture.

To change the visibility of a post, click to highlight your desired option. Type in your text if you haven’t already, then click on Publish.
Public — This is the default setting for posts and comments that you’re happy to be broadcast (visible) to everyone in the Fediverse and in the human Universe. See the details given above under “Posts are public by default.”
Unlisted — Anyone who comes across the post or comment can see it, but it won’t appear in the Explore, Local or Federated tabs.
This can be useful for replying in threads, so that you’re not filling people’s timelines unnecessarily. Keep in mind that all POSTS (meaning posts and replies) made by you are visible to your Followers in their Home timelines.
Also, as replies on Mastodon automatically contain @ followed by the name of who you’re replying to, the person whom you are replying to will be “alerted” (by the @ mention tag). So, if you leave the @ [ name ] in the text box before typing in your reply, the person you’re replying to will get a Notification that you replied.
If you are following someone, you will see their unlisted posts and replies to you and anyone else in your Home feed, unless you have turned off “Show replies.” See screenshot 9 referring to hiding replies under the Home timeline.
Likewise, if someone is following you, they will see your unlisted posts and replies in their Home feed, unless they have turned off “Show replies.”
Also, be aware that even if a post or a reply/comment is unlisted, if someone not on Mastodon finds and goes to your Mastodon Profile page, they will be able to see or read your unlisted posts and replies (on the “Posts and replies” tab of your Profile page).
An unlisted post or comment is indicated by an open lock icon. Don’t think that Unlisted means your post or reply will never be found by anyone. They can be seen on your Profile page even to people not signed into Mastodon.
Note that hashtags in unlisted posts are not searchable.
Note that unlisted posts and comments can be boosted to your followers.
Unlisting is just a way of hiding posts and replies from the Explore, Local and Federated timelines.
