The most common mistakes are showing people your product- don't show them your product, it's sort of like telling them bout a feature.

The instant they say something you don't expect or already know, you should drop into detective mode.

Who you talk to is just as important as what questions you ask and what you pull away from it.

Given the huge number Xbox owners and how many of them love gaming spectatorship, its a natural fit to bring the Twitch experience to the 360.

You have this idea that you think is awesome. You want to have that broadest group you possibly can. You don't want to just talk to 1 type of person and learn that, you want to get familiar with the space.

The question is, once you have this idea, is this enough? Is it something people would actually switch just to have?

This is true for most new products. The majority of people you're competing with are non-users. They are people who have never used your service before. And what they say is actually the most important. What they say is the thing that blocks you from expanding the size of your market with your features.
