A Google a Day:

I don't like Google's solution to today's April 12 question. But it's really just due to the ambiguity of the question itself.
My standard for top performance search answering:
- single set of search terms
- answer comes up on 1st page search results
- answer can clearly be read from the search preview, without clicking through to a website
I'd only rate myself a B on this question. It took two sets of search terms for me to find the answer. Better than Google's 3 though.
