I suppose there’s an element of preference as well. If !myinterest exists and is limping along with 80 subscribers and a post once a month, is that less discouraging? Maybe 300 subs and a post every other day is adequate? At the risk of scope creep, maybe the answer lies in more data and options to account for the preferences of those new to the Fediverse.
Fight the good fight, friend. I need more posts about old TV shows and niche hobbies, so we just need more decent people, however they arrive. :-)
