Nope. I don't even conceal my real name. I even have published my kids' names online. People are generally much too paranoid about privacy online.
Until you find out how annoying and unsettling it is to be stalked online. I was rather blasé about online privacy until I learned that valuable lesson. I'm certainly not a hermit on the interwebs even still, but it's made me think a bit more about the stuff we put on the net. So yeah, maybe I am a bit paranoid but it's for good reason. There are a lot of twunts out there.
