PoisonedMinds has a breakdown of time spent on modern web design.
In light of a recent article, I especially like the “Time spent trying to get the layout to work using only CSS…” and “Time spent trying to get the bastard to work in…”.
It sort of reminds me of a pie chart I made of what Caitlin’s cat does during the day when I was writing some PHP charting software. Nowadays I’d just use PHP/SWF Charts for that.
