Search behavior over the couse of a day

An anonymous reader writes: Chris Harrison has built a visualization that explores what people are doing online over time. He explains "Search engines are the gateway to the internet for most people, and so search queries provide insight into what people are doing and thinking. In order to examine millions of search queries, I built a simple, cyclical, clock-like visualization that displays the top search terms over a 24-hour period." Interesting to see that the masses online have fairly coherent and consistent search behaviors. He also investigates the notorious AOL data-set.
