Joined sh.itjust.works since it’s located in North America, has open registration, and the admin sounds like he knows what he’s doing running a server. I’ve stayed 'cause it’s been stable and I like the admin’s vibe. It and lemmy.world seem to have become the main large “general purpose” instances since they both have open registration.

I also have an account on kbin that I’m not using much at the moment. I think that site has lots of future potential, though.
