I get your point and I agree with you to some extent. Especially this part:

"Rewards are going to the same accounts"

That is very true. I have seen pretty awesome curation going on though, but the "inner circle" or whatever one should call it are still pretty much the same people. The same guys are voting on the same users back- and forth, over and over again... But I can't see how that would ever stop or change, so I am just glad to see all the positive vibes across the platform.
