I think one interesting dynamic is that publishers have visibility. I am mostly thinking about books. There are book clubs and book reviewers. I wonder how many people buys a book just because it's on Oprah's Book Club. (apparently, a lot, http://en.wikipedia.org/wiki/Oprah_Book_Club http://en.wikipedia.org/wiki/Oprah_Book_Club). And then my next guess is that there are PR people at the publishers that push reviewers and book clubs to endorse their book. I think you can draw an analogy with content aggregators like Digg or Reddit. There too many books for the average person to consume so they look to some book club or reviewer to tell them what they should consume. I believe the publishing dynamic may change if a book "content aggregator" received a wide following. Is there a digg (or reddit!) for books? If not, someone here want to create one? :)
