To me, the smaller userbase is actually a real problem. I’m willing to stick it out and hope it grows. But for over half of the subreddits I subscribe to, the corresponding lemmy communities have 0 posts this last week.
Yes, I don’t need 10k comments on my posts. But memes or mainstream news was never the big value of reddit for me - I can get these anywhere. Instead it is about the niche communities with a few thousand subscribers. And for now, I still have to use reddit for them.
