What is Mastodon?
Mastodon is Twitter-style social networking combined with email-style instanced servers. It's named after the metal band, but themed after the extinct megafauna.
How is it like Twitter?
You post relatively-short status updates, and you can see a streaming list of your friends' status updates. You can keep notifications (replies, boosts, favorites, and DMs) in a separate column.
Mastodon's statuses are called "toots", like Twitter's are called "tweets". A toot can be up to 500 characters long.
Mastodon also supports hashtags, which are words prefixed by #, like "#gameing" or "#pineapple". You can click on a hashtag to search for other posts containing that tag.
How is it like email?
Each Mastodon instance is independent but networked, like email servers. If you sign up for an email account on gmail.com, you don't automatically have an account on hotmail.com or aol.com, but you can send and receive messages to and from users on hotmail.com and aol.com.
Likewise, if you sign up for an account on mastodon.social, that doesn't make an account for you on every other instance, but you can talk to users from other instances and they can talk to you.
You can make accounts on multiple instances if you want to talk about different things separately. You could have an account on https://cybre.space to talk about tec, an account on https://elekk.xyz to talk about games, and an account on https://mstdn.social for general chatter. You have to sign into each account separately, and keep each open in a separate browser tab or window.
Keep in mind that in general, when talking about Mastodon, "instance" and "server" mean the same thing.

Great work! ❤️
@Mastodon very nice guide. I am quoting from it regularly. As opposed to @TrustedSara I find this to be uncomplicated and easy for the average person to comprehend. But, maybe I view it that way because I understand it well.
I just wanted to say, good job! I appreciate this effort.
@Mastodon queeee, esto es ilógico, tengo que crear una cuenta para cada comunidad a la que quiero ingresar??
Uno donde crea todas esas cuentas?
