I have nothing against Blogs and actually think it's a great way to let people know what you've been up to, and is pretty fun in terms of interaction. On the other hand, when your entire contact list is made up of people like on TDP's list, then I would be shamed to admit I even use it.
Plus, MySpace.com isn't exactly the sharpest knife in the drawer.
For those who said something like "well Blogs are just for people who are F*cked up and can't socialize with people normally" well, that's just plain wierd. Some of the most talented, and basiclly most charismatic people I know are online. I am heavly into gamedev and basiclly just ambition to succeed in whatever "geek" thing I do, and you just can't find those type of people in your school. I socialize plenty, have no trouble doing it, and all the people I surround myself with have no trouble doing it. Tons of t celebrities Blog, and using the same thinking, I'd have to assume they have no life!
