I appreciate the effort on spreading the word about HTML5 and CSS3, but there are things in these articles that bother me a lot.
Overuse of CSS3 animations brings back the 'skip intro' flash experience of the 90s, and I'm terrified that since it's a new toy, there'll be a tendency to overuse it.
In this specific example, the speed of the animations (too slow) hinders usability and becomes distractive.
