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

You want to learn about what's already in their heads. You want to avoid putting things there.

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.

The other mistake I think people make is talking to who's available rather than talking to who they need to talk to.

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

That's actually one of the most disappointing things about doing user interviews and user feedback, which is why I think... people don't do it. You're going to get negative news about your favorite pet feature most of the time.
