UPDATE; the event was a blast !
The gathering was stimulating, dynamic and well organized , and CSI was the perfect venue. It was so much fun, linuxcaffe is hosting a follow up evening, this coming Wednesday June 11th. No advance booking required, no fees, but an opportunity to pick up the conversation and have a refeshing something.
In the spirit of Open, and in the form of bar-camp, the Shuttleworth Foundation and the Centre for Social Innovation are hosting OpenEverything

An un-conference exploring all things Open, the event will feature talks, sessions and "speedgeek" presentations by some of Toronto's most impassioned proponents of a more open society. There's only room for 60 participants, and the registration of $40 includes coffee, snacks, a hot meal and ideas that will change the world.
