Fanpage Analytics
Yet another public source for information on a particular business/subject/whatever: Fan Page Analytics. It currently only analyzes Facebook Pages, but it seems that there are plans for Twitter and MySpace as well.
Here is a world map of the relative popularity of the NOKIA Fanpage (which is quite consistent with the world map that Google Insight draws for Nokia)
Note: I adjusted the contrast of the generated image, as the full color scale was not used well by the visualization.
And this is a list of related fanpages, i.e. a list of pages that Nokia Fans are more likely to be a fan as well:
Maybe even more telling might be to chart the Fan Pages which people are less likely to be subscribed to. We will see where Peter Warden is going to develop that tool.
