So I've been playing with Google Maps a bit, even dreaming of creating an MT plug-in for it. Truth is I'm delaying trying to tackle this in the hopes that one of the brilliant and much much more talented plug-in developers create one.. MemeFirst has a nice entry about trying to find 1 Liberty Plaza on a number of different maps. This seems to some kind of Turing test for maps of NY. In their quest they've uncovered this cool NYC mapping tool.
