Tried three tests: my own name, "Clojure tutorials" (something I've been looking for recently), and ""ORG directives in assembly code" (something I had trouble finding recently). Scores - Google 1, Yahoo 1, Bing 1. Not a very large sample space, to be sure, but still it was very hard to tell the difference, and by the stats, a lot of other people have had similar reactions (with a slight lead for Google).

Maybe this means we should just stick with the company we like the best? Google it is then ;)
