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.
Technically, “enforced pay it forward” is called credit. Your debt would then be “the amount you still have to pay forward”.
Of course, this defeats both the spirit and the purpose of a pay it forward scheme.
