i don't think blogs are beating regular news outlets because of some sort of unbias reporting. If blogs had the reach and power as mainstream news outlets they would suffer from the bias problem as well.

The true reason why blogs are beating regualar newspapers is because newspapers are trying too hard to win pulitzer prizes. Blogs give the same information but in a more convienent fashion that allows you to get the main idea with good commentary in a quick fashion.

So I think it has more to do with form and structure of content.
