Now it's a matter of sustaining and slow growth. Hopefully. Best thing you can do to see Lemmy succeed is participate: comment, post, doomscroll All+Top Hou ;)
It'll take a while for some of the smaller communities to get critical mass. And that's okay, probably. Critical mass is here for the larger topics already. I'll do my best to help :)
This helps, but ideally lemmy should make some changes that give smaller subs more equality with bigger ones in the sorting.
Right now even if a small community is active, it just gets drowned out by the bigger ones, even in your subscription feed.
I think they are working on tweaking the hot sort a bit more to make it more representative so the huge communities don't drown out the smaller ones especially in subscribed
Or some equivalent of a multireddit where you can look at some quiet communities as a block.
