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.

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

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.

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

People don't like silence, so they'll keep talking to fill the void.

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?

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.
