@lucxx very much feel you tbh.
For all its fucking flaws (and there is so so many) reddit does fill a niche for me atm. Where I can have one account on the site but be present in many communities that are focuses on special {thing}.
For me thats Lolita-Fashion or sewing as of late. I can ask people there on specific stuff like dyeing techniques...
The microblogging side is where I can talk to friends. Though I do use a seperate account to share my stuff from Sewing or other DIYs.
But yeah when my bubble would not reach into mkab (misskey-absturztaube) I would not have found as many people since puni has a kinda big service going lol.
Found one person, I made friends with as well, to talk properly on sewing.
I know lemmy is a thing as well but its the whole network-effect thong all over man...
