This morning in the commute from Watkinsville to College Park for the conference, Laura mentioned a person that she is associated with on Twitter... Caroline O'Bannon. Then I walked into my first session and who do you think is presenting? COBANNON....along with Cerese Godfrey. The presentation listed a number of great tools from Ustream, Plurk, Slide.com, Toondoo, goanimate, etherpad, rock you, gizmoz, tagul, wall wisher....and so much more. I would link them all here, but I really think you should see her presentation- which is a wiki set up via a glogster poster....You will not be disappointed!
