What a great group! I haven't been on Classroom 2.0 for even 24 hours and already 5 people have bothered to welcome me with friend invites.
I signed on to Ning just to see what the system was like after hearing about the Classroom and Library 2.0 projects. My big question was whether Ning was worth the new time investment, especially given that I have a hard enough time carving out moments to write in my blog (it still hasn't become a habit for me).
These first five invites, however, have certainly answered my question. This community is active and welcoming! I look forward to exchanging ideas with everyone here.
