The value axis shows the search traffic relative to 2004.04.04, which is around the time that the 1.2 release came out. That is, according to Google WordPress is now about 37 times more popular than at the time when 1.2 was released, and it’s growing steadily. Yay
In absolute numbers, this is about 12 000 searches per day in November 2008.
