The pool of people you care about is going to shift over time.

The one question you can't ask is, "Is this feature actually good or not?"

It's one of the most validating things you can do for a product is go out there and get them to commit to pay you up front.

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.

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.

Recording interviews is like magic. a) It stops you from taking notes in the middle and b) you can play that recording for people.

Who would you talk to? That is the first question for almost any startup that you need to answer. Who is my user and where am I going to find them?
