What Dan said. The evidence that DVORAK is faster that QWERTY is... poor....

comment Unintuitive order of vi directional keys
That's basically it. vi copied ADM-3A. ADM-3A had that format because of the way control used to work. What the control key used to do was drop bits 6 & 7 of the ASCII character. That caused HJKL to map to ASCII control codes 08 (backspace/left), 12 (linefeed/down), 13 (vertical tab/up) & 14 (form feed/right). Since those four keys were on the home row you could sit there holding control and move around very quickly.

comment Does animating statistical data make it easier to understand?
++ to this. Hans Rosling's animations are showing you things that you cannot see on a static graph. To extend Tufte's metaphor they're 'data animation' not 'decoration animation' (cf infovis-wiki.net/index.php/Data-Ink_Ratio)

comment What's a good modification/alternative to differentiating categories by colour when the number of categories grows large?
@Tyler - References? I've just shown #191919 (90% black) and #33333 (80% black) squares to four people and nobody was able to successfully differentiate them without having them side-by-side for comparison...

comment Login using one of two mutually exclusive fields
There is a downside to the single field option though. You cannot supply hints on the input type that would supply content-specific data entry for numbers vs email addresses (e.g. the different iPhone keyboards you get).

comment Product design materials
For example - what's the right number of materials for a chess board. I've seen chess boards that vary from printed black-and-white squares on a piece of paper, to a lovely piece that was made of 64 different kinds of wood / wood-treatments that was a demo piece for a furniture restorers skills. Both were the right choice for the context.

comment Product design materials
It may or may not be groovy depending on what the design goals were. There isn't "a" rule. The number of materials depends on the interplay of dozens of things.

comment How many images should a slideshow carousel rotate automatically?
I would second what @AlexeyPegov said. In every usability test I've done with carousels the people using the site have either not taken notice of them, disliked them, or not actually followed up on anything past the first image. Yet to see them work in a useful way. Don't know why people use 'em.

comment Simulate Eye-tracking by Photoshop filters?
@GaëlLaurans - Yup. Completely right. As I said "mild oversimplification" ;-) And obviously some cues for gaze path must be coming from the peripheral vision - motion across the visual field being the most obvious example. But I think that things like the F-pattern show that there's a lot of higher-level drivers for gaze path too. Visual frequency is, I think, unlikely to be a useful cue by itself.
