According to a study in Melbourne, blogging actually improves the mood of the blogger and makes them feel less isolated.  Could this really replace Prozac?

When I was a depressed, crazy, hormonal teenager, I kept a really good online journal.  I had regular readers who became some of my best friends even though I'd never met them before.  Having their advice, and my roots in the gospel, I was able to find a way to be happy being myself, and in a sense found myself. 

I also found that I always had too much on my mind, and that writing for a good hour or so was a good way to clear my mind and discover what I was really thinking, as opposed to trying to pick at a piece of string in a tornado. 

So here's the question:  Is it blogging, where you have access to anonymous people whom you can write about everything to and they can respond, or could this be another reason we are encouraged to keep a journal?  I simply prefer typing a journal because I can type faster than I can write things down, and my thoughts run pretty quickly.
