Web 2.0 Goes to School

I am trying to weave through all the Web 2.0 material that is available - and have listed concrete examples that have worked well in my classroom over the last 3 years.  Our school will be piloting an iPad cart in 5th grade next year, and I'm looking for ways to roll my "in the clouds" curriculum into this new area.  Any ideas??
