Clay Shirky has a couple of very interesting books:
"Here Comes Everybody" and "Cognitive Surplus" in which he explores the emerging potential for collective action and cognitive collaboration through social network sites, shared media and the like. His work may be helpful for us as we think about using technology and informal networks and how that relates to networked and collective leadership.

Here's a great introduction to what he's thinking. Enjoy!
