I found this a little interesting. It triggered something in me that made me want to go out and find numbers! I settled with making a counter for Britney Spears popularity which does a query on Google and takes the number of hits.

It's just a dirty shame that making any kind of long-term statistics will be hard due to the screen-scraping nature of the application. Anyone's who has ever tried scraping IMDB knows what I am talking about. :)

I like it.
