How transferable is this account that I'm posting from across the fediverse? - Lemmy.World

I’m glad this community is here because I feel very stupid. I’ve seen videos likening the fediverse to email and phone networks. Some of what I’ve seen implies that not only are lemmy instances connected but lemmy instances can also be connected with mastodon, peertube, and others. Is this true? How to I connect to other instances or even other platforms?

We had a similar thread recently here: discuss.tchncs.de/post/27868444

You are registered on a Lemmy instance and from those you can only follow communities (that are structured the way Lemmy communities are, but the backend doesn’t need to actually be Lemmy), not people. Mastodon, PeerTube etc. are places where people post to their own profiles, so you can’t follow those from Lemmy, you need to create an account on e.g. Mastodon to do that. You can combine both worlds with some backends (piefed, mbin, friendica).

How does interoperability work between different fediverse services? - tchncs

I’ve only used Lemmy amongst the panoply of ActivityPub compatible social networks; am I seeing and interacting with posts from Mastodon, Friendica, et al. and just not aware of it?

Cool, so I probably want mastodon and lemmy accounts, which I already have. But I’ll try to avoid making new accounts if they aren’t necessary. Are there any worthwhile sites that are compatible with lemmy?
As I wrote, try looking for a piefed, mbin or friendica instance you like.
