Tell people about your idea, or keep it to yourself?
xenoterracide: depends on the product. the likelyhood of competition, and what kind of secrets you are devulging. I wouldn't tell people how to make your product. But, I believe someone said it on a thread recently (maybe blog entry) that not talking is overrated (paraphrase). Don't give up patent secrets or what your trump card is. But 99% of people ain't going to hurt you, your biggest problem will eventually become needing to tell people.
