Yes, I think it will change. There are plenty of obscure reddit subs that do just fine. People on there get "rewarded" (though they work for free) finding good links also. It will happen here, too, but the evolution will take time. In my mind, the so-called "circle jerk" postings so far are not just that; they are defining and exploring the attributes and possibilities of Steemit. As more people understand what it is and how to use it for fun and profit, the action will move into different areas. We've already seen the big expansion of the introduceyourself tag this weekend, which is very encouraging. If new users continue to come in and continue to post, a lot of topics will build up and people will gravitate towards the ones that fit their interests. Plus, the voting power should be much more spread out by next month.
