For now, at least, thats not me. For a couple of reasons. If it matters, its because of my job, where I live, and my natural shyness. I'm a doctor, which makes me a bit uncomfortable about being all stalk-able. I also live in one of those cities where everyone knows everyone, especially in my profession. As for the shyness, well, it is what it is.
Why a blog, and why now? Firstly, because as I said, blogs have changed. No longer just personal diaries, but now appear to also be soap boxes, and and I want me some of that! And as for the timing, I guess its a time of great personal change for me, so it just seemed right.
