Good examples. I pretty much agree with all you say, but didn´t have live experience to support my ideas. I would also say that where you are located or the group you are talking to, is important. I live in Spain and I pretty much could give away hundred of copies of our business plan, and no competitors are going to rise from that. I think that even in SV I could pretty much give the general idea and I´ll bet that no competitors would rise either. At least not in the same form, execution surely would be different. Not because is a new idea, but because it´s not something you can hack in a month with some ruby gems, it needs some investment in coding, and even more effort on market development. Execution and product vision is everything in startups, unless you are talking of a new feature in an established industry, AND talking to people related to the industry. That´s probably the place for an NDA.
