I gotcha. Fwiw I kind of agree, even beyond Lemmy I’ve been a little surprised some of these sites/instances haven’t done more to tailor themselves to accommodate more folks or focus on specific demographics.
That’s supposed to be one of the big perks of the federation approach, being able to create more distinct communities, but outside of a few, they largely seem to run the software as-is, maybe with some backend adjustments to help reduce the costs of operation or the like.
