Releasing your business plan into the public?
webwright: If I described Google to you before they launched, could you have built it?  Would you have?  How about Digg?  The iPhone?  WordPress?  Facebook?  Amazon?  Name 10 amazing startups and try to imagine how it could have hurt them if their biz plans were public.Almost anyone who could possibly be a threat to you if they had your idea ALREADY HAS THEIR OWN IDEAS.  Even if they don't, presumably you have dozens of competitors-- 1 or 2 more isn't going to change your shot at success.  If you don't think you have ANY competitors, you are either stupid about your market or you truly have an invention on your hands and you should keep quiet.Talking about your idea a LOT will make you smarter about your market and increase you shot at success.  Do it, and do it a lot.
