I started on lemmy.world but am currently writing this from discuss.online, a lemmy instance I found in the greater NYC area because that’s where I’m based. It has the same access to all the communities and content that lemmy.world does and because it’s nearby and has fewer users it’s fast! Signing up and setting up my subscriptions only took a few minutes. I still have a lemmy.world account, but I don’t need to use it all the time.
