Congrats and kudos to the creator and developer of the Googlewhack, Gary Stock.
Recently, the 500,000 "whack" was recorded on the site. Googlewhacking has been around since 2002.
How do you Googlewhack?
The 500,000 Googlewhack was "spacefarer tomboy."
Googlewhacking has even inspired a one-man show titled, "Googlewhack Adventure."
Finally, if you're a Googlewhacker and would like to reminisce about the early days, here's the original Googlewhacking page from 2002. You might also want to take a look at a SearchDay article that Chris wrote about the "sport" of Googlewhacking in early 2002.
