The threat to women bloggers

The Washington Post has an article about the threat to women bloggers - as the blogosphere grows, it grows nastier. I've always been a little circumspect about what I say, because I remember how nasty Usenet was. But for the women profiled in this article, it is a whole lot worse. A lot worse.

Why are there so many sociopathic trolls on the Internet, anyway? Underneath the veneer of civilized day to day life, are there really that many people who are totally unhinged?
