An anonymous reader writes: Washington Post: Some of the folks responsible for developing and promoting e-mail, e-commerce and social media are banding together in an attempt to save the U.S. Postal Service, the institution arguably most threatened by the technological developments of the past few years. As mail volume continues to plummet and more Americans use the Internet to pay bills and keep in touch, Google executives, social media experts and some of the most passionate tech evangelists are planning to meet in Crystal City in mid-June to sort out how to save and remake the nation's mail delivery service. The conference, PostalVision 2020, is designed to bring together the people who understand what this technology has done, is doing and will do to digital commerce and communication in America. The conference is scheduled to hear from Vint Cerf, Google's chief internet evangelist, and Jeff Jarvis, who writes the popular BuzzMachine.com blog and is an associate professor and director of the interactive journalism program at the City University of New York Graduate School of Journalism. He has written and blogged several times about whether or not the nation still needs a national mail delivery service.
