Greg presented a GIFT (great ideas for teaching/training) session on Web 2.0 Applications at an international conference. The unique format of the sessions(multiple condensed 8 minute presentations repeated for changing audiences) offers an idea for teaching in itself, and posting the "same" content multiple times allows us to critique his presentation and see how it evolved.
