Happened to come across couple of posts that talked about Google Trends and how they can be utilized to check the popularity of few things:
On the Web, If You're Not Growing, You're DyingBollywood Actresses: Who's Google Hot and Who's Google Not?
Interesting to see how the popularity of actresses on the web really indicates the career graph... movie hits.. some big gossips about them.... some changes in their personal life has really kicked a new interest in finding about their profile :)
I did the same with Intuit and surprisingly found Canada providing more web traffic to intuit searches than US. Popularity seems to have decreased but time to get back to the old ways :).. Also happy to find India being a great traffic provider :-)
