Classroom2.0 on Ning

I've recently joined a Ning community, "Classroom2.0," as you can see by my new badge on this blog.
Classroom2.0 is a "social networking site for those interested in the practical application of computer technology (especially Web 2.0) in the classroom and in their own professional development."
I think Ning has great potential for teachers/educators setting up their own social networks and exploring the potential of Web2.0. I've recommended setting up a community in Ning for a couple of local groups of educators, getting started in social networkiing.
