Blast from the past came up in #teachingopensource today, the Personal Learning Environments page on Wikiversity. Cormac Lawler, you have been one of my grad school heroes since we first met in Taipei in summer of '07, and I continue to search for a dissertation project Just As Cool for my own studies. I salute you, sir.
Also, this quote still holds true.
"...the exact technologies that are in use at any particular point in
time don’t matter as much as the fact that it is people being connected
through them. Tools come and go constantly, and the only constant is
that the people are the important part of the equation." --D'Arcy Norman
