I subscribe to new communities community https://lemmy.world/c/newcommunities plus using lemmy explore site https://lemmyverse.net/communities. Also tagging people when you talk to them. So when you meet them again you have context to get to know people in lemmy. So they become more like real people vs just usernames providing content. In my experience if you put a little work into it. You find friends and lemmy starts to feel like an old school forum.
