Both are federated right? Getting a bit confused - are they interchangeable? Can I view lemmy posts/communities in Mastodon? Similar to how I can view lemmy.ml content with a lemmy.world account?
Lemmy is more like Reddit, Mastodon is more like Twitter.
In other words: Lemmy has communities (subreddits) and hierarchical comments for each post. Mastodon doesn’t have either of those things, but it has following users and following hashtags.
Despite being different, they have some interoperability because they use the same federation protocol.
Glomming onto your comment here…
…I discovered that something called Peertube also exists, using the same federation idea/protocol. And it’s to YouTube as Lemmy is to Reddit.
(Man, I never thought those school word problems would ever be relevant…)
But you need to host the videos on your instance and foot the bandwith bill, which will prevent it from taking off like Youtube. Too expensive for anyone outside of gigantic monopolistic companies.It relies on peer-to-peer, not hosting.
BTW: there is also a Facebook equivalent (Friendica, GNU Social, Dispora and Hubzilla), a Instagram equivalent (Pixelfed) and a Instant Messenger (Matrix)
While Matrix is federated, it uses its own protocol,.not ActivityPub like the others you mentioned.
