Stack overflow got exposure to thousands of developers from day one thanks to Joel/Jeff. If they'd stuck the site up anonymously it would be nowhere near as well used now, and might even have never got anywhere without an initial critical mass of users and questions/answers. The UI might keep users interested once they're there, but it's not going to get them there in the first place.
