I am not sold. This reminds me of Reddit gold a bit. I think having exclusive content is less open source and I do not think that is what Steemit is about. I do enjoy the idea of separating yourself from the herd and Steemit has its own share of bad content IMO. I think it is hard to find good content anywhere and those that provide it will be rewarded in time. This idea may work in the future although it must be earned but who is deciding what is worthy and what is not?
