It was my privilege to meet and talk with Ulises Mejias a few months back. He possesses one of the sharpest minds in the field, and brings a lot of unique perspectives to a broad range of issues that are dear to my heart.
He is leading an online panel discussion that looks simply fabulous. The names say it all: Stephen Downes, Ross Mayfield, Ziauddin Sardar. Check out the program page at:
Attendance is free. This should be one hot session.
