Give users what they actually want, not what they say they want. And whatever you do, don't give them new features just because your competitors have them!

In many cases, the more you try to compete, the less competitive you actually are.

Just make people better at something they want to be better at.

It does not matter how awesome your product is or your presentation or your post. Your awesome thing matters ONLY to the extent that it serves the user's ability to be a little more awesome.

The best user experiences are enchanting. They help the user enter an alternate reality, whether it's the world of making music, writing, sharing photos, coding, or managing a project.

Code as if the next guy to maintain your code is a homicidal maniac who knows where you live.

We are all human, and caring about the way something looks and feels does not mean we're superficial--it means we're human. We don't need to exploit sex to recognize that a certain amount of sexiness is both pleasurable and natural.
