reasons why I won't steal your idea

Since I'm a software architect and a web developer, I get often approached by people with their new ideas. In most cases, for some quality feedback, and on lucky days, for a rough quote about the costs of such a project. These people are usually very secretive about what they have, making me explain to them that it's far from my interest to steal that idea. (...) Focus on your product, and don't worry about me stealing your idea. I won't. I have at least five reasons not to.
