With SN you can login with nostr and cross post to nostr. I use it as a daily driver next to primal and amethyst. They have daily rewards, for good posts and a solid community.

They have user funded territories with games and competitions. I post in music pretty frequently and have one of my tapes pinned at the top.

When I post long form notes, I do it through SN to take advantage of both audiences and incentive structures.
