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

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.

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

Twitch launched in June of 2011, and our growth ever since has exceeded even my expectations, which were not small. A year and a half later, the community of broadcasters and viewers has multiplied hundreds of percent.

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

Sales is this cure all for this problem. Get people to give you their credit card and I guarantee you they're actually interested.

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.

People who are using your product and putting up with all these issues, means that they are not actually the biggest problems.

The most interesting things you learn in an interviews come from the: 'interesting', 'tell me more'

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.

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