So I'm trying to piece together what Mastodon is, and I this is what I think it is so far:
Mastodon is like Reddit, in that there are separate servers like subreddits. Unlike Reddit, you have to join those "subreddits" with a new created account each time, so you need multiple accounts across different communities. This is why Mastodon says they're decentralised: none of the communities are connected to each other barring the framework of Mastodon itself. Mastodon "subreddits" are then like Twitter, in that there's a bunch of people "tweeting" (I think they call them tooting... I don't like that name) on their accounts that you can follow individually. Like Reddit, you can see the latest "tweets" of the entire "sub" which on bigger communities is very much a blur.
I feel like I need to expand my online presence to more socials, and maybe this will either help people figure out what Mastodon actually is or make people correct me on what it actually is.
