I’m subscribed to 50 total communities / magazines across Lemmy and kbin and honestly, almost every time I hit refresh (while using subscribed and sort by new - I understand there are some front page bugs) I get new stuff to read or look at.
I haven’t felt like it’s dead here since I signed up and the engagement has just gotten better as people get more comfortable with whichever software they’re using (either Lemmy, kbin, or even Mastodon). It’s not an overwhelming amount of posts like trying to read Reddit by New.
And I look regularly for other communities I might be interested in.
