I felt a little like that. I miss a few of my favorite subs. The “break up” feelings went away when I stopped lurking and started participating.

Stardew Valley is my go-to. I found Firewatch really easy to get lost in too.

It’s been good so far. I’ve just been lurking, looking at different communities. I’m a long time Reddit user and like others have said, I’m going to miss the really niche subreddits. Hopefully the platform keeps growing!
