I would say it's actually in the order that it is on the site. Making lists were the top thing that everyone did, far and away, for personal use and for public display. Others liked having a central place to send recommendations from, for movies, restaurants, books, TV shows, podcasts, and more. The activity feed and broadcasts seem to be good when you have a lot of followers (as some early adopters did), so we expect that to grow over time.
