I have seen from others that kept watch to see if their beta was visited and they were not. I don't believe they test out most of the web applications that get submitted. So not having one didn't hurt you at all. They say it is good to have a beta, but I don't really believe it. Even in the interviews it is said they spend less then a minute checking out any beta. It is apparently just not really important.
Good luck to all of you. I think they mean well when they say they make lots of mistakes.
