Funnily enough I myself wondered if this would happen a while back ago: with all this talk of the death of the mainstream press, I started wondering if this meant that since on the Internet you can focus on a specific audience with specific beliefs seeing as you don't have to make up for massive overhead costs like your average newspaper or TV station (assuming it's not supported by uber wealthy interest groups - do I REALLY have to mention names?) the "press" would eventually lose even the slimmest illusion of objectivity and thus people would only get info by people with the same beliefs as them, with all the bias that implies.
Naturally, whenever I tried discussing this with anyone, my concerns were always dismissed with arguments such as "Dude, the media is incredibly biased NOW. When this fragmentation you speak of occurs, we will FINALLY be able to separate the crap from the REAL news!". While I do agree that there is great bias in the media (even here), I don't think having a huge number of super biased sources for you to choose from is the way to go.
I guess we'll just have to wait and see what comes out of this. Hopefully as there will be demand for biased news, there will be something to cater to people who prefer more balanced treatments. Even if not, as long as like Dave said the several points of view are expressed in a reasonable manner, the discomfort inherent in reading something that doesn't share your view point becomes bearable. Naive? Maybe, but just as television, radio, rock and roll and video games HAVEN'T lead to the moral collapse of humanity as many feared, I don't think this will.
