Sadly, my German isn't the best or else I would've looked more into that one. ;)
I applied for an account over at Beehaw.org, but they're slammed since they have been hit the hardest by Reddit users (as they are the closest culturally to Reddit).
I'm also not 100% sure if I'll switch or not... I've had this account since 2020, which makes it a relatively old account in Lemmy terms. Not that I've used it much, mind...
