lemmy, but I still check reddit after Iβm done here
Reddit is still a lot more crowded, but I prefer Lemmy simply because of no ads and the actual conversations that you can have with people.
I would prefer Lemmy/Kbin but all the communities I actively followed on Reddit are still there
Honestly, I root for lemmy and use it daily. However, Reddit still wins on pure content and niche communities.
Imgur was bought out and they nuked all the top all time photos and gifs, I call that the start of the downfall.
