@jcrabapple People are not dumb beyond help. They're unaccustomed to the question of what server they want to sign up at, and it's likely that a critical-mass service is going to have to do away with that step (e.g., by auto-assigning a server). It may also be possible to get away with a UX tuned for the most tech-basic user, which prompts people to enter a username and then choose a server from a wheel-style interface, thus building their entire username without thinking about *servers*.
