Microsofts Chris Pendleton , the technical evangelist for Bing Maps, led a fascinating panel at South By Southwest on Sunday morning with map experts from Foursquare, Twitter, Navtec and Flickr talking about the future of mapping. The panelists discussed their anticipated future at which online maps are overlaid with more and more data: personal history of places youve been, social history of places your friends have been, and cultural history data of locations.
