Craigs List is growing in use?

I use Craig's list a lot, it is easy to use and it is free. I have gotten results and that is why I think this next info item is happening:

Heather Dougherty writes, "U.S. searches on the term 'craigslist' have increased 105 percent for the week ending March 14, 2009, compared with the same week last year." Meanwhile, queries for 'myspace' decreased by 7 percent during the same period.
