I have been playing a bit with the great PyGoogle wrapper and I found another great idea by the great Mark Pilgrim: Google Neighborhood.
The idea is very simple, trying to find the list of sites that are “neighbor” of a certain site/resource web, following the simple rule that a neighbor is a resource that is referenced and references the originating resource.
From this very simple idea we can start rambling on other possible applications, like some of the usage that people find out in google local. Check this description for having a glance at what I am striving for in STAMPS. All comments are welcome.
