I got a great email today from Cbrown1023. He did a Google search and a result from Wikibooks appeared first, even before any results from Wikipedia! What's funny is that it's not on a topic that I would consider to be a particular strength of our collection. Part of me hopes this page is not being heavily linked to as an example of the worst parts of Wikibooks, but when you see the page in question you might have that thought too. Another reminder of how much more work we need in order to make a great library of free books!
My next point of interest is to wonder why Cbrown1023 was searching for information about nuclear war? Do the WP people know something us WB folks don't?
