Web 2.0.....

I've spent a good bit of time this summer catching up on reading some journal articles and perusing some blogs that I never got around to during the school year. I have been paying lots of attention to the Web 2.0 articles to find ways that I might effectively incorporate some 2.0 technology into my school. My questions are: Who has already been using web 2.0 technologies succesfully? What types of things are you doing? Are you the one leading the Web 2.0 bandwagon at your school or are there teachers out there working with you?

Any thoughts.........
