At this conference we also debuted AttendeeBee, a mobile/social/cloud app attendees use to tweet, share their location, and rate sessions. Attendees get more points the more they use AttendeeBee, increasing their chances of winning our giveaway, an XBox/Kinect bundle in this case. At the Neudesic booth, attendees can see the entire conference at a glance on a large monitor, including a leaderboard. This provides an element of gamification. AttendeeBee worked pretty well on its maiden voyage and we have some good ideas on where to take it next.
