Conference Season: CommunityNext PlatformMax at CommunityNext in Sunnyvale. The underlying drive behind the entire event is to discuss some of the intricacies behind a locked-down platform like Facebook's. CommunityNext is interesting in that Noah Kagan, one of the organizers, did a really good job of finding, and bringing a lot of the upper tier Facebook Platform developers to Silicon Valley from Philadelphia, Boston, New York City, etc.
If nothing else, CommunityNext is rumored to have great parties, and there just so happens to be a BBQ later today down here in Sunnyvale. It's somewhat late to suggest that everybody I know to attend, so I'll just mention that you're missing some good fun in South Bay, and leave it at that.
