If you're hearing a lot about the fediverse these days, you should know: Mastodon is not the whole fediverse and the fediverse is not simply a Twitter replacement. The fediverse is an entire ecosystem, built on something called ActivityPub. Learn more: https://www.eff.org/deeplinks/2022/11/leaving-twitters-walled-garden
Leaving Twitter's Walled Garden

@eff I found this a bit confusing. It says that you can following people on different instances and they can follow you, but then also says you might pick your instance based on a common interest. I think that could use some additional clarification as to what benefit you get from being on the same instance as those with whom you share a common instance, if it’s not the ability to read their posts.

Is it that your instance’s feed acts like a curated list of content relevant to that interest?

@captbaritone @eff I also found it confusing, the instance has more to do with the security of the account's data than with the matter at the end of the day. Federated networks are not walled gardens. The instance is also a way to micro manage issues related to user posts.
