Please don't maintain a blog just to improve your job prospects. Not that I think it won't work. But it's an arms race, it only helps you until everyone else starts doing it as well. The cost of playing along is that everybody who wants a job needs to spend more time doing something they don't care about, and "has a blog" becomes less valuable as a signal to employers. ...besides, I already have a blog, and I don't want to lose that advantage.
