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.

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

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

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.

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.

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

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