I don't use reddit anymore, I still have an account but I stay logged out unless I need to see info in a thread that is some fix that I need because they won't let you see that now without being logged in.

Lemmy does have way less content and way less people but you can find them if you look. I suggest changing your default sort to either "active" or "new comments". I use "New comments" this sort will show all threads that have any new comments on them so I can find the active conversations right away. I have been very chatty on Lemmy this way.

Lemmy has its own set of trolls and extremists, they aren't conservative trolls like you see on reddit, they are extreme left all the way around back to Fascism, but I see you are on db0 so, you won't see the more troublesome instances.

EDIT to add: My main in on Db0, and I still use that on mobile, but I ended up making an account on lemmy.world just to use this Lemmy skin https://old.lemmy.world/ Old Lemmy was what got me out of reddit forever, there is something very comfortable about this skin and it made my transition very smooth.
