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

The crucial people to get your product started for the first 6 months are not who will be using it 3 years later.

A goal of Twitch is to be wherever gamers are, whether its on laptops and handheld devices or integrated into gaming consoles and software.

I wish I could tell you the recipe for figuring out who the target user is for your product and who your users should be, but... there isn't a recipe. It comes down to think really hard and use your judgement to figure out who you're really building this for.

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.

If you just talk to who's easy to talk to, you're not really getting the best data.

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.
