This is true when you're just trying to have a preliminary discussion, but when someone is actually going to start working for you and get access to your code and internal documents, then it makes sense to have an NDA or an employment contract with an NDA clause.

Otherwise I agree that you should have your lawyer look at it and probably just pass altogether.
