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

Users think they know what they want, but you get the horseless carriage effect where you're getting asked for a faster horse.

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.

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

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

The pool of people you care about is going to shift over time.

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