I came here after the recent post-Inauguration bloodbath, when they permabanned many of their veteran, high-volume posters like me (12 years, 900K+ karma).
Lemmy definitely feels more free, and i certainly dont miss the puns, trolls, bots, Russian Propaganda Farmers, novelty accounts, etc.
I really miss the guitar subs, though. Reddit's are active and fun, and a great place to interact, get advice, give advice, watch players post performances of their progress, etc. I've seen several very young players turn into known talents, like Grace Bowers.
Lemmy still has a lot of growing to do, but so did Reddit when i started.
