Bez, you know I've got nothing against you, mate.
But the rise of blogs is one of the main factors killing journalism and destroying the reliability of information.
(following not directed at you personally, and based on solid professional experience)
Blogs print whatever bit of information comes their way without getting two sources, fact checking, contacting people involved for comment, etc. - the ideal hallmarks of real journalism. From there it hits Twitter, etc., and then the "traditional" media feels it has to pick it up and next thing you know, entirely baseless rumors become fact in people's minds.
Furthermore, "traditional" media have lowered their standards to compete in the 24-hour news environment. Everybody loses.
I've seen it happen. In my work, I've won lawsuits over stories that evolved this way.
I've even seen blogs created just for the purpose of starting rumors to advertise various businesses mentioned in passing somewhere in the text of their stories!
So no, if anything, a lot of blogs are contributing to the dumbing down of society.
Sorry for the off-topic rant, but I couldn't let that comment go unchallenged.
