I think the whole "ideas are cheap" meme gets overblown a bit. There are certainly both good and bad ideas. But that's a bit missing the point really. The reason I won't sign an NDA is that it is a great liability at a very low perceived value. They are, by their very nature, usually brought up very early in a relationship, at a time where there is little commitment from both sides. Yet the ramifications of signing it are potentially vast. That mismatch just seems way out of proportions, unless there's something exceptional about the whole situation (Like, if the person asking for the NDA is someone famous, that I have respect/admiration for).
