This is why I don't share really good ideas.<p>You can say that ideas are worthless, but when you put a good idea in the head of someone with more time, drive, or resources than you, you will create competition (and possibly put yourself out of business before you start).<p>My last couple of business ideas (which now make me good money) came from someone blabbing about it on an Internet forum. My idea was a little different of course, but it did directly compete.
