I think a good way for buddypress to become better than competition is to have a feature to share spotify playlists.
People who sign up to social networks are often new with things, so they use spotify which is the new big thing. I know there's a website where you can share your spotify playlists. Why not make it a feature of buddypress?
This from a guy who doesn't even run a buddypress website... so you know it's good :wink:.
