The problem is with the money. The solution is thus in the same place - the money. We need to separate the investment returns from the curation returns. In other words all investors should be rewarded equally, according to the size of their investment, and curators should be rewarded according to the quality of their curation. I think investors should however retain some non-monetary priviledges, such as the ability to bump a comment (their own, or someone else’s), to the top of the list of comments.
