By the way, about that spaghetti bowl style, here's a fascinating comparison of styles between Google Maps, Bing Maps, and Yahoo Maps: http://www.41latitude.com/post/2072504768/google-maps-label-readability
I loved the Boingboing.net review of this article. Best excerpt from that review:
...it's intriguing how each service's maps artistically reflect their corporate operators' natures. Google's is perfectly organized and functional, devoid of embellishment. Microsoft Bing's is beautiful and overdesigned, with a subtle palette of lavender and teal. Yahoo's looks like someone vomited a spaghetti dinner in Carrot Top's hair.Classic!
