See, the issue here is that it's not really curating, like @trufflepig, but rather just paying popular people. The equation's not fully released, and without more info it's hard to know for a fact whether or not it's working right, and the lack of transparency into the system (only the top 100 plus your own account doesn't show that much info, all things considered) means that you'd never know if the system's really working at all.
