This past weekend I was one of the producers of EventCamp.org where we utilized video with some silly pre-event videos to get the audience excited about the event. Then onsite we used the sponsor Livestream to stream video and audio to our virtual audience who joined us via twitter. Livestream plus a small DV Camera captured and can archive the sessions and interviews for later viewing and to build excitement and carry the message and information of the event for the months in between events helping keep the community flowing.
