All the recent coverage of PleaseRobMe.com has focused on one particular idea of what can be done with realtime datamining of location data. (And how long until we see mashups combining PleaseRobMe.com with social cataloging sites such as LibraryThing?)
Where My Ladies At? (link goes to John Bollozos’ descriptive writeup) is another such site – it mines data from apps such as FourSquare and Gowalla and compares it against a database of female names in order to identify places where lots of females are at a given moment. I’m really at a loss to say more about it.
See also Jim Bumgardner’s “Mayor Of The North Pole” for a perspective on forging location data.
