Blogging addiction?

I was wondering about the possibilities of being addicted to blogs, and so I did what I usually do and googled it ("blogging addiction"). What I found are lots of people blogging about their addiction to blogging. I also found an interesting article from the NY Times, "For Some, The Blogging Never Stops", which tells about a guy who locked himself in the bathroom with his laptop while he was on his honeymoon so he could blog (trying to hide it from his new wife...boy, is she in for it). It also confirms that most people who blog do it for themselves "just to get it off my chest", rather than because they have an audience. Personally, I don't find that to be my experience at all. I am writing solely for the tiny audience I have amassed (all 2 or 3 of you) and in fact struggle with what to say that won't be too contoversial, or reveal the extent of my mental instability. I think blogging is a little like standing naked, or with very little clothing, in a crowd. But I wouldn't feel comfortable with that either. So again I wonder why I'm blogging...Is it just a habit now? Is it becoming an addiction? Is it because my fans would miss me? I certainly find myself more comfortable with commenting on other blogs, the cloaked effect. Or maybe because I have no original thoughts, but can respond to stimuli (rather like a planaria).
