I don't necessarily think these two contradict each other--they're really about different things. Sivers' article is concerned with the psychology behind motivation while this article and discussion is about the fear of idea stealing. I'm firmly in the camp of sharing ideas with anyone who will listen. And, ideally, with different types of people. If I can concisely explain my idea with someone who doesn't know a browser from a modem, then that's when I know I've really thought through my idea. That would be impossible if you're walking around with entrepreneur paranoia.
