The big difference is on Nostr you have to do all the work yourself. There isn't an algo you can kowtow to to get easy follows. You have to post things people want to read.

Eventually, I'm sure there will be people who figure out the easiest way to get tons of followers and I'm sure they will be promoting their book or videos or classes. Even then, it's probably going to require more work than just posting thumbnails of yourself with your mouth hanging open.
