I think you can follow Peertube channels and write comments but not post videos. And you can't access Mastodon nor Pixelfed.
Lemmy is centered on the concept of ActivityPub groups. While Mastodon etc are about individuals, they don't use that concept (with their toots) and since following accounts isn't implemented in Lemmy, there is no way to properly interact.
Though there are other software projects. MBin combines both. And Piefed wants to get there, eventually. They already hook into a few more things, but Mastodon or Pixelfed accounts currently aren't properly supported either. But Mastodon people can write replies to our posts.
It's a bit complicated. And I think ActivityPub is fairly low level and broad (I think). So it's really down to the individual implementation and whether two projects agree to do something in a compatible way. And write code for the specifics of some content types.
Small nitpick. Lemmy communities are present on Mastodon and can be followed and replied to by Mastodon users. One can see a comment written by someone from Mastodon. We only can't follow a Mastodon user or Mastodon tags from Lemmy
Example: https://mastodon.social/@VoxAliorum@lemmy.ml/115167313865117114
Also a Mastodon user can follow a Lemmy user.
The replies will federate but not the threads. So for example, the Mastodon user will get notifications about replies to their comments and the Lemmy user will get notifications of the Mastodon user. However, the two users will see the conversion displayed quite differently, especially if there are more than two users in the conversion.
Is this a real follow or is this just a redirect? It redirects me to my profile.
For some reason if you copy the url when on Mastodon.social and paste it into browser it redirects.
If you want to see this community on Mastodon, go to some mastodon server, search for
fediverse@lemmy.worldand scroll down. You will find your post with our responses etcThanks. That worked.
It is a copy of your real profile from lemmy.ml that users on mastodon.social can interact with. Those interactions are then copied to lemmy.ml
