Atlassian Summit 2011 opened its doors today to a sold out audience at the InterContinental Hotel in downtown San Francisco. Today’s draw was a combination of all-day product training courses, a packed kickoff party, Atlassian partner meetings, and a collision of geekery with a slightly smaller and lesser known event, Apple’s WWDC, which is taking place right around the corner at the Moscone Convention Center.

Tomorrow is the kick-off for all-day sessions beginning with a keynote address in the morning. Stay tuned for some exciting announcements. Now it’s off to the Summit opening after parties!
