A month ago, FortiusOne founder Sean Gorman said on the company blog that they would port GeoIQ, their (ironically) very cool heatmap tool for Google Maps, to KML. In a post today, Sean shows they’re making great progress. Here’s a heat map he posted correlating concentrations of single women and highly-rated bars in the Lower East Side (my old stomping ground!).
I think this tool is going to be such a hit when it is released as a KML network link.
BTW, if you have data that you think is made for mashing up to get this kind of visualization, FortiusOne is looking for content contributors to test their new collaborative geospatial data repository, GeoCommons. This all sounds so very very promising.

This reminds me about heatmaps showing World Wind servers usage (you can see where are people looking at)
