The name comes from a fictional character of mine. I guess he could be regarded as an alter ego of sorts. I used his name for my ID because I wasn't in the mood to think of something clever or borrow something from somewhere else.
When god hands you a lemon, give it a gigantic bite.
As for the shyness, the way I got over it (and I still have problems with it) is to really just realize that the other party is, after all, human. They have many of the same ideas and thoughts you do; that should be basis enough for interaction.
