For the most part I have, there are a few subs that i’d like to see here but Lemmy is still kinda new so it’ll take time.
I’ve also dropped twitter for mastodon but same issue there too.
I really like the federation feature like the ability to respond to Lemmy via mastodon.
Go to whichever comment/post on a lemmy instance you’re trying to comment on and copy the link in that little colorful icon below/above the comment/post (that’s the fediverse icon and the fediverse-wide interoperable link).
Then just paste that into your search field on your mastodon instance, and the rest is self-explanatory from there.
