Pretty good, though I’m not mainly using Lemmy directly. I run a Kbin instance that I’ve been using primarily, but I’ve also been testing Artemis with the developer’s artemis.camp instance, and I have Infinity for Lemmy signed into my lemmy.world account.
There’s less content here than on Reddit, but I think it’s higher quality. There’s less trolling and shitposting here (unless seeking it out on purpose then there’s plenty).
It’s great if what you want is Arch Linux and everything that comes with it. Things might break from time to time.
If you want something more stable I’d go with Fedora or Debian.
Good. Mint sucks. Fuck Intuit.
Use Lunch Money or YNAB.
