Thanks to my buddy at Virgin for the info:

Challenging how knowledge is created. proudly presents its first seminar in the 2007 seminar series – Challenging how knowledge is created. The keynote speaker for the seminar, which will be held in Adelaide, Perth, Sydney and Melbourne, is Jimmy Wales, founder of Wikipedia.

Jimmy Wales, the man behind Wikipedia, has a vision. The vision is for every person on the planet to be given free access to the sum of all human knowledge, and Wikipedia has been described as an exercise in the democratisation of that knowledge.

Wikipedia is also seen as being at the forefront of Web 2.0 – characterised by the new literacies of the 21st Century of inclusion, collaboration and participation.
