Idea: Building a sickmap

I just twit­tered this idea but I want to push it further:

Mon­i­tor twit­ter for tweets about being sick. Cross that info with the user’s geo info. Col­lect all this infor­ma­tion. Then build a sick map of the world about where peo­ple are feel­ing sick. Show hot spots, trends, etc. I’ll add it to the list.

Maybe I’ll have insom­nia one night and ham­mer it out.
