BookWorm would likewise be bad on so many levels. First, it would imply that I read a lot and while I have stacks of books I intend to get to - someday - I never seem to get around to reading them. And secondly, and perhaps most importantly, we're back to frumpy Church Lady - boring.
Turns out they don't go with a user name anymore. It's just your first name.
