There’s close to 30.000 communities on the Lemmyverse, most of them on servers/instances different than yours. You’re on lemmy.world, one of the most “general” instances that took on a lot of the migrating users so there’s going to be a more “reddit” style userbase there.
Check out lemmyverse.net/communities and look for other communities for your favorite topics. I’m sure you’ll find different communities with different type of users. For instance, I browse !technology from several instances. Many of those communities I don’t bother commenting in, simply because it’s not my crowd. If there’s a good post I want to discuss with likeminded people, there’s always the cross-post function.
