Thing #2 Web 2.0 - Why care?

I am already feeling relieved a bit from the Web 2.0 frantic -ness. Just knowing that others are struggling with the "how to fit it in"and "what impact will it have" questions makes it seem more manageable and exciting. We are planning to create and write a program for a Web 2.0 classroom as a big experiment - a playground for trying out web 2.0 apps. I'm excited and hope to get more comfortable with some of the newer 2.0 ideas by participating in 23 things.
