Not OP but... I just recently created https://kbin.social/m/Fedquestions for questions about how the fediverse works on a technical level. So far I have three subscribers including me, but one of them really helped out on my only question so far!
I really enjoyed reddit's niche fashion subs and trying to recreate some of that over here. Was a consistent reddit poster but went cold turkey on reddit and doing my posting here now
Ahh I know of it, but too expensive for me. Anyway I am happy to have you and I do hope that such a fashion community can grow here too. Streetwear and fashion advice has inspired me before to try different things.
