The value (controversy) of Geo-Spatial Databases

This article in Newsweek is a good article on the topic.

An interesting website is listed in it.
Fundrace This uses the FEC's rule of logging campagin contributions to a map, allowing you to see who is contributing to whom and how much. I can now see what many of my neighbors do, get some idea on their financial background etc.

I know it goes against free speech and the principles of technology, but have we reached a stage where we need regulation (or atleast think about ) how & how much information can be interlinked?
