This year, my first full year, I attended the conference almost non-stop to get as much in as possible. I also volunteered hoping my limited knowledge would serve and it worked out okay. I learned so much.
Major take aways were Chris Dede's need to unlearn, which is threatening like exposing your "self" through using web 2.+ tools whether for teaching or for participating in professional development events such as this one. I just bought his new book, Digital Teaching Platforms http://store.tcpress.com/0807753165.shtml
Machinima examples and explanations made me want to delve into digital storytelling. Watching the machinimas together at the Be Epic Japanese-themed park reminded me of the movie the Wedding Planner where people watched the black and white movies in Golden Gate Park.
I also want to become an Agilista like Bill Firehawk describes. Using SL as a collaborative platform is the way to get good things done. So many more things to follow up on. The First Responder Island, Virtual Harmony, and practical applications that could be used by my institution if they get serious about support are some key examples that stand out. Whew!
