Servers that can federate over ActivityPub protocol. Any server that uses ActivityPub can be considered part of the fediverse.
Clones of corporate owned sites: twitter (mastodon, misskey), tumblr (wafrn), reddit (lemmy, piefed), facebook (friendica), plus others
Yes, it is
Bluesky isn't, since they use a different protocol, but it's possible to bridge and interact with it. Wafrn does it.
This is the biggest "it depends" situation. For instance, by default, lemmy ignores most posts from mastodon and similars. However, mastodon users can post to lemmy communities if they use the proper
@, but they cannot specify a title - their post body will also double as the title. They can also reply to comments, they're easy to spot because they always have an@userwhen replying.Some server types integrate the different things better than others. Friendica and Wafrn seem to be the best for "variety integration".
