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

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.

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.

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.

Who you talk to is just as important as what questions you ask and what you pull away from it.

The most common mistakes are showing people your product- don't show them your product, it's sort of like telling them bout a feature.
