Great article advocating for responsive web design. "Again, it's true that responsive design and device-specific experiences can offer us a way around many of these problems. If we can tune the size of a button to a particular environment, then we don't have to accept blunt, across-the-board treatment. But the number of devices we have to support will only increase, and customizing for every possible scenario could quickly become unreasonable. Even if we are able to provide perfectly tailored design at the execution level, there is still value in thinking about tempered, universally accessible design at the conceptual level. Additionally, just because we can tailor design to particular experiences doesn't mean that users will not carry expectations over from one experience to another. The boundaries might blur whether we like it or not."

"For example, when Twitter was redesigning their desktop experience, live usability tests were projected on the wall of the development war room, as the developers were working. When something interesting happened in the test, the user researcher (observing from the war room), would say, "Hey everyone, you need to see what's happening here." Real time user research is a component of a Lean UX process."

Makes a case for designers and developers working very closely in a collaborative way

"Most people-imagine this: you can't draw very well, but even if you can draw very well, suppose you come in and you've got to put together animation or drawings and show it to a world-class, famous animator. Well, you don't want to show something that is weak, or poor, so you want to hold off until you get it right. And the trick is to actually stop that behavior. We show it every day, when it's incomplete."

Could be useful as we're considering how to increase user registrations.

Makes a good case for responsive web design, and not trying to target specific devices.

Slides #135ff have patterns for mobile experiences

different reasons for prototyping and types of prototypes to meet those needs

Marty Cagan again, this time making a case for live-data prototypes in order to facilitate user testing and A/B tests.

Good thoughts on different levels of prototyping for different needs.
