I too am a fan of the wirearchies to describe the self-organising collaborative connections that come and go with the flow of change. The analagy is even stronger (in my view) if you look beyond the need (and the opportunites) for collaboration. The wirearchy of connections need to form not just to meet the collective needs/goals, but to support people's independent work both within and accross company boundaries (the work that we do in parallel). As much of a fan I am of twitter and their ability to connect people, surpise and inspire - I can't help but think the chaotic nature of such networks will not be *the* solution for the outer layer of your 'onion'. I also think that we can do better than to 'cooperate' at this level.That we can get to a point where we can provide environments of mutual support born out inter-connected work (co-working / co-learning / co-developing). That we can create ever evolving wirearchies of connections based on the links between our work - not just by our shared (broader) interests or via personal connections. Thoughts? (am I making any sense, it is getting late! :)
