Social Networking for Educators

Classroom 2.0 looks like a great resource for teachers who want to integrate more technology into their teaching. There are multiple forums where educators can join discussions about things like which smartphone apps other ESL teachers find useful or the pros and cons of using cellphones in class. It's easy to find and join conversations, because everything is organized by tags. I like the idea of having such a large network of educators to interact with, but also appreciate the way there are smaller groups formed around shared interests or topics, so a sense of community can exist.
