I know steemit is a new site and things will probably change about it as it continue to evolve but what i think it's lacking is the chat room environment that other sites have. People are still flocking to face book for the chat rooms. Steemit is more of a blogging site and lots of people don't want to blog the prefer more of chatting in groups with friends. I think if steemit adds groups to here a lot will tend to spend more time here instead of just making a post and running back to fb.
