I've been here for a bit more than a week now and my biggest advice and is to take it as it is. Take a deep breath, accept that this is Lemmy and not something else, and that you're feeling it out. This is not relearning a bike, this is getting in a peddle boat for the first time. Similar, yes, but also it's own thing.

Set feed to All. Scroll. See interesting topic you want to see more, subscribe to community. Interested in specific topic? Search for community in communities page. Once you gather enough subscriptions, set feed to subscribed. Scroll.

Yeah it's different, you'll burn in pretty quick though, just have to get used stuff being spread across a bunch of instances. It feels pretty natural after using it a while. The designers try to make it easy. It's kind of like email where each community has two parts to its name.

ok, so i have been here for like a whole hour now so i'm a pro! Jk I still don't get a lot of it but I did find this cool map that shows you large communities! https://lemmymap.feddit.de/
