I think Mark Britz is right about the savanna. Seen as risky, and probably rightfully so. And worthy. What interests me is how to move the enterprise towards more informality, which to me means more choice, independence, community and lightly constrained funkiness. This won't happen because we like it. It will happen because employees like it AND they and their enterprise see measured benefits. It's going to take some guidance systems that help employees become more self-reliant and active in their growth, reference, and communities. Frank Nguyen and I built a little tool to help people think about informality, and formality, for the enterprise-- http://frankn.net/yinyang
