Package Tracking Thru Twitter

Found out through a tweet from John C. Dvorak that the twittering public can track their packages through Twitter. Following the instructions, the way to do it is to follow @trackthis on Twitter. You then send a direct message (and not @reply) containing your package's tracking code plus a short phrase describing the package (useful when you start getting the updates). A direct message will be sent to you every time your packages moves locations. The service currently supports FedEx, UPS, USPS and DHL tracking. Neat, huh?
