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.

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.

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

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

The Twitch community loves watching video games, chatting, and broadcasting. The average viewer watches over an hour and a half of video each day. Over two-thirds of our logged-in users chat each day.

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.

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