A truly awesome bit of tech here. Graffiti Markup Language (a new XML protocol) makes for some pretty awesome tech. This is just another one of those data streams that will continue to make headlines in 2010. This along with GPS tracking (expertly put into practice by people like @jaybregman 's company e-courier.co.uk) mark a new era of using the data that our ever digitizing world creates, for new and in many cases more creative applications than the tech that creates it! Thanks to thewayoftheweb for bringing this to my attention!
