At TEDxUSC, business professor David Logan talks about the five kinds of tribes that humans naturally form — in schools, workplaces, even the driver’s license bureau. Initially, Logan’s discussion may come across as a how-to for ascending ‘tribal stages’ and a bit reductionistic, but around 11:00 the message gels, and it’s a good one.

Below that is a video, also from TED, with author Seth Godin discussing how the Internet has revived the human social need for tribes and people to lead them. If you’re interested, you can download a free PDF “Tribes Case Book” from Godin right here.
