Google just came out with a new service called: Google Trends Labs that lets you search trends in search queries. I found this to be very addictive, sort of like comparing Chuck Norris to Mr. T or Cindy Lauper to Madonna, but on a more serious note. It was also great to get a better understanding of individual search terms and what the media is using. See above for a comparison of nonprofit terms (I'm surprised charity is so much higher than nonprofit). Another interesting search I tried out was looking at the trends with "hurricane", "Katrina", and "donate" around Aug and Sept of last year.
I'm interested to hear about other thoughts on how to use this new tool?
