I can’t (and shouldn’t have to) carry the entire weight of a fandom on my shoulders. Until there’s more activity here on those subjects, I have to at least keep an eye on Reddit.
What I always do when I can however, is I try to do POSEO to raise awareness: by which I mean, I post my opinions or ideas or stories in my own site (or in my Masto main) first, and only crosslink on Reddit. I was thinking of doing the same with reply comments as well, but dunno how much would that promote interaction.
