Could the Creators of Google Maps Reinvent Email?

Google Wave may take over Facebook, Twitter, and email by integrating and reinventing the functionality of all three. This video is targeted at developers, but gives a good overview of this new product (still in the early stages of development). At UC Press, those of us in web marketing currently manage professional and personal Facebook and Twitter accounts, home and work calendars, and personal and work email accounts. We look forward to the day when these are all combined in one application. Could this be it?
