Yesterday Classroom 2.0 hit 25,000 members. I was remembering that we thought the network was large when we had 500 members, and certainly many things have changed in the last couple of years. When I started Classroom 2.0, nobody knew what a "Ning" was, and there was a *lot* of skepticism that social networking had any place in professional development. :)
If you're willing, would you share how social networking--Classroom 2.0 or any other network you belong to--has impacted you, both personally and professionally?
