I see this kind of mail/post all the time. Some business guy thinks all that's necessary for a successful web-startup is a good idea. He then can find a lowly developer who takes care of those pesky details while he ponders whether the header should be more blueish or not... I don't mean to be rude, but these ideas are usually crap and without a technical (co)founder, it's not gonna happen.
Also: Ideas are worthless. Execution is everything.
