Special guest star Jason Olson explains Open Space at PDC2008.  The "Birds of a Feather" Sessions of the past were considered too structured and too boring.  Enter Open Space, the new (to the tech industry) way to create ad hoc "un"-conferences.  Open Space will be located in the track lounges and not shunted to some back corner held in the middle of the night.  Topics are driven 100% by attendees.  No demos, no podiums, just conversation.
