Whenever I hear the phrases "rock star developer" or "code ninja", I think, "Oh, they want some young fresh-out-of-college full-of-himself developer who thinks a language named after a rock is the wave of the future."<p>Jokes aside, those phrases raise red flags in my mind. I think maybe it is that from such an employer, I would expect to see the occasional presentation with swear words ("We're all adults, here" -- "Sure, but you act like you just left your parents' house, and with your first taste of freedom, you express your naughty self."). Ah, that is the word I am looking for: professionalism. I have a hard time taking them seriously.
