New to Classroom 2.0

So I am a newbie, signed up for Classroom 2.0 as part of a class assignment. I am excited to see how other educators are using 2.0 tools in their classrooms, and I look forward to collaborating online. This is my first year as an elementary school librarian and I am always looking for ideas for lesson plans and activities, and how to integrate technology into the curriculum. So I would love to know what people are up to, and I will definitely bring my questions to Classroom 2.0!
