I think there are 2 groups coming from reddit. 1- Users wanting a more niche community (think early reddit) 2- Users trying to turn Lemmy into present day Reddit. Theres a good amount of communities that are carbon copies of reddit subs. Personally I think the reddit has morphed into something toxic (Ive had a reddit account for 15 years). While its good have growth, nobody wants to use a site that is so popular that Aunt Betty is chiming in with her love jesus memes.
