If you want an idea of just how BIG this conference is check out the dining hall or the keynote address attendance.
There are over 7,500 attendees here for 4 days of SharePoint.
The day started early with breakfast followed by the keynote. No major reveals but some nice additions coming along the track.
From there it was into a number of sessions including information about SharePoint Online, Business Intelligence Dashboards and improved productivity. All extremely worthwhile.
An even bigger day tomorrow with a full day of session followed by a party in Disneyland. Obviously Mickey must be a big SharePoint user to throw open his park (free) to all attendees!
