Later this week, the Berkman Center heads west to San Francisco. We’re hosting an unconference on Mobile Identity, led by fellows Doc Searls, John Clippinger, Mary Rundle, Urs Gasser and others. It’s free and open, but you should sign up if you’d like to come, as space is limited. CNet is kindly hosting us. We’re also planning an informal reception for Berkman Center alums and friends; let one of us know if you’ll be in San Francisco on Friday night and we’ll ping you an invite.
