Peter U 05 December 2011 Fantastic article: inciteful and provoking! Nice to read how current technologies give us the power to really make a user’s experience a better than good one, in quietly cool ways. But I am struggling with the subtleness of your “Revealed content pre-loading” demo: I can see no performance difference between the two at all. Is this down to my very fast connection negating your hard work? Thanks again.
