Based around following people: not communities or topics. If I follow a person, I have to see all of their posts no matter how unimportant to me it is. I might like a person's input on star trek, I really don't care if they're drinking their second red bull that morning.
There are tags, but no voting, no sorting, and no moderation, so they're mostly garbage.
No way to see what's popular: or sorting based on voting whatsoever. Updates stream in, which means you can't subscribe to more than a few people unless you want your entire day to be gone.
Length-limited content emphasizes gotcha soundbytes, and not discussion.
No tree-based commenting: meaning I have to click into a lot of threads just to see replies.

AFAIK, some instances have a way to view popular posts on the "/explore" page. The instance I just migrated from had it, but the one I am on now doesn't, so it isn't all of them.
