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

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

The question is, once you have this idea, is this enough? Is it something people would actually switch just to have?

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.

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.

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.
