To Blog, or not to Blog... Ah, that is the question

So I have thought of "blogs" for some time as a means for people with no life to post their useless thoughts for all to see knowing full well that no one cares, and no one is really listening. That said, I vowed never to start one. Now that I am, does this mean I have no life? Does anyone really care? And is anyone really listening? Who cares?
