I had joined Reddit twice in my lifetime but was not actively using it, and maybe that’s the reason I’m not very familiar with this forum culture.
I would say that Lemmy is by far the most responsive SNS in terms of the community engagement that I’ve ever used.
That may depend on the community.
I have the opposite experience. I mostly post in niche communities on Reddit, and I find I’m ignored or get positive replies. On Lemmy I get responses, but odds are even that the response is snarky or removed.
I hope that will improve as the user base grows and we get more niche communities here.
