I'm going to be flying to Mountain View this evening to attend the Open Science Summit. Various PGP members have attended and spoken in previous years; this year I'm up and scheduled to give a 15-20 minute talk Saturday morning (in the 10:45am-12:00pm PST grouping).
Open science is of course one of our core motivations as a project, and I look forward to meeting many like-minded folks there. Live streaming of the summit should be available at this site: http://fora.tv/conference/open_science_summit_2012/livestream
For twitter users, the hashtag du jour will be "#OSS12". Last minute tickets if you want to attend in person are here: http://opensciencesummit2012.eventbrite.com/ (looks like $300 at this point).
