If anyone comes out with a website that purports to provide quick access to information, it'll inevitably be compared to Google (or Yahoo, or Live Search, or whatever comes next). Slate's comparison is actually even pretty close; the author took the examples provided and tweaked them slightly.

For example, "running 4mph 30 minutes 5'10" 160 lbs 40 year male" provides an answer, but "golfing 4mph 30 minutes 5'10" 160 lbs 40 year male" doesn't. I think that his conclusion was the most interesting part, about "the eternal problem for any wannabe Google competitor[: ...] Google can easily co-opt such improvements -- and suddenly everyone's got a better Google."
