Blogs are good for you?

On the news it said that blogging is supposed to be good for you. Why? It is that you get a release when you blog about stuff that really drives you up the wall, or comforting when you blog stuff that you really wouldn't be brave enough to say in person?

Mmmmmm.

It also said that most blogs become dormant about a month after they are created. Mum turned towards me when the newsreader said that. Guilty as charged.
