Google Insights

Today I discovered a useful tool published by google: Google Insights. I am sure marketing people will enjoy it ;)

On the open source side it has been used to determine the popularity of Linux across the globe. It is particularly interesting to see which country has the more interest in which distribution.
My favorite Linux distribution Gentoo is not presented in the article, but you may find the related stats here.

The link between term popularity and headlines on the graph is especially interesting as it gives a good insight of what happened.
