What the title says, basically. On reddit there’s r/cassetteculture but for the moment I can’t find anything like that on lemmy. Would be nice to have a community like this here! If there isn’t one, should I create it? I don’t have that much experience with moderating or hosting communities, so I’m not sure about it at the moment…
Even common-themed communities consist of a few dozen users here (bots included). Most probably you will be the only active user in your new community.
I would suggest participating in some more wide-themed community where your cassette-fetish wouldn’t be an offtop. Plus you might find other people who are interested and this will help you to adequately assess the need of the new community.
