I think you raise an interesting point. There are actually TWO problems here. One is that there is possibly a bias based on the content submitter/creator.

But the other is that, people who are followed will naturally get more votes, just because they get more views. Is that a bad thing? I dunno. But what if it got to a point where there were enough different people being followed that the only way onto the first page is by being one of them. That kindof sounds like a problem too.
