Why blog?

Why is it that a person suddenly feels the need to start a blog and (hopefully) share their thoughts with the world? Is it that they are lonely? In need of attention? Maybe in the middle of a busy world, in what seems to be a perfect job, surrounded by self-important folk, I need a space to be truly honest.

Seems to me that the older we get, and the more successful we are, the only time we are truly honest is when we are with kids. I don't have any of my own, but I am lucky enough to have two small friends with whom I can really be myself. The rest of the time I have to 'put on a face' - the "professional" face, the "boss" face, the "good daughter" face or the "god I hope I am hiding how bad this date is going" face.

So let me know - how honest can you really be in a blog? Do you self-edit? Does a fear of being identified limit what you say? Guidance for the newbie welcome....
