The logic is really simple. Bloggers don't mean jack. They are tiny tiny tiny piece of the electorate that only the most politically passionate read. It's the Dean voters. Edwards has already gone after that market and thats why he's running third.

Most people do not read blogs. But there is a helluva lot of people on Myspace. So, he decided to go where the numbers are. I'd rather have 10,000 female supporters from Facebook than 1,000 female bloggers mostly reading each others stuff.

The social networking model is far more successful than any blog out there, so it was only smart of him to build his own social network than depend on a bunch of amateur pundits.
