Number of Wikipedia pages indexed by Google
This is the number of Wikipedia pages in Google's index. There is some AutoIt code at the bottom that will scrape the number of results from each datacenter at Google, but lately the easiest route has been just been grabbing the numbers from the CSV file that WikiPulse generates. You can also do a Google search for site:wikipedia.org. An amazing and steady increase.
Wikipedia derives 66% of traffic from search engine referrals, and 50% of that traffic comes from Google, meaning 33% of all Wikipedia traffic is from Google referrals alone (according to Hitwise - therefore these stats apply to U.S. traffic only, and that is only around a quarter of total traffic).

You can get a more accurate number by polling each Google datacenter individually. The following basic AutoIt 3 code will paste the results to your clipboard.
