For some harmless time wasting (or is time wasting never harmless?) try Googlefight at http://www.googlefight.com/ You type in two words or phrases and it shows a little stick-figures-fighting animation, then it shows two bars, indicating the number of hits on Google for the two terms. Thus one sees that there are, for example, a lot more hits for "information literacy" than for "information skills", and "e-literacy" vs. "information literacy" is no contest, but "information literacy" and "media literacy" are closer (though with IL still the winner).
One can also do sad stuff like putting in one's own name and the name of someone else and shouting "yay" when one gets more hits than the other name. Not that I'd ever do anything like that, of course.
