I prefer Lemmy, but unfortunately it is missing a lot of the communities I liked on Reddit, and there doesn’t seem to be as much content. When I’m looking for information on a specific topic I’ll still check out Reddit but I haven’t logged in since the Reddit drama and don’t plan to. I do hope Lemmy gets bigger, though.
I don’t think it’s the size but more the number of communities and how active they are. So if there are more people here it hopefully means there will be more active users as well. And perhaps more niche communities.
