ONE WAY to measure the residual effect of a major conference is by the connections you make--not by the business cards you collect. As I head off to Reboot 9, I snapped a screen that shows my Facebook network. It's dominated by James Corbett, one of the most effective social facilitators in Irish tech space. It will be interesting to see if I connect with another mother node, perhaps a Canadian who ties into the podcasters who are already part of my Facebook network.
The Facebook Friend Thing is here: http://friendthing.trigse.cx/ and it's designed to do more than show Facebook data.
