comment Why do checkout processes place payment info last?
Yes - there are token systems but they cost money to run and implement. They're less exploitable than storing the CC numbers - but they still make it much easier for folk to do bad things to your customers if the site gets hacked. The point I was trying to make was that the decision on where to gather payment info isn't a "free" one on the technical/business side ;)

comment Is a short stay on Web Page always bad?
Yes. You optimise for the goal not the length of time. For example when building apps for intranets I'm generally trying to encourage people to complete their tasks as quickly as possible. Short times (that achieve the goals) are good.

comment Monitors display more colors than human eye can distinguish
In addition to all of the above there is some evidence that we see some frequencies better than others (e.g. we are better at differentiating greens than we are blues and reds because of the frequencies the rods and cones in our eye respond to). So the colours that we can differentiate are not spread evenly over the whole visible spectrum.

comment How to archive paper prototypes and physical objects from design process?
This is pretty much exactly what I do. I double check before throwing away that nobody wants them. But,basically, if they've not been used in six months they're either irrelevant or already embodied in code.

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...
