Sure, usernames are meant to be more creative and unrealistic when compared to our real names. I mean, I've never seen a user named "Johnathan Fitzgerald" or whatever. But, even so, I do find myself making assuptions about certain people, based on their username. I find myself thinking that some nOOb with a stupid name is actually stupid; without even knowing them. C'mon, who is going to take a name like "Sasuke_is_hawt" seriously? But really, do you ever prejudge - or ignore - someone on a forum, just because of their username?
