Steve Krug quotes:

Designers love subtle cues, because subtlety is one of the traits of sophisticated design. But Web users aregenerally in such a hurry that they routinely miss subtle cues.

If you're going to implement video, do it as well as YouTube does it or don't do it at all.

I don't think there are as many usability issues as there are tactical or strategic decisions related to whether incorporating social networking into your site is going to help or hurt.

When you go to a site, you usually run into usability problems pretty quickly. They're not hidden. They're not complicated. They're not baffling. They were in the design or crept into the design.

The general reactions were that the video was either not going to load, or be painfully slow to load, or would require a plug-in users didn't have. YouTube changed that, because it just works.

The more you watch users carefully and listen to them articulate their intentions, motivations, and thought processes, the more you realize that their individual reactions to Web pages are based on so many variables that attempts to describe users in terms of one-dimensional likes and dislikes are futile and counter-productive. Good design, on the other hand, takes this complexity into account.
