Two requests

I don’t know if anyone can help but I received two research requests and promised to use this blog as a knowledge gathering device.

1. Does anyone know examples of companies that have a significant amount of self-organisation in their structure (either the whole group, a sub division or whatever). One example so far has been W.L.Gore which imposes a strict size on any division, splitting and breaking when that limit is reached. Another example would be the Grameen Foundation.
2. There is considerable interest in the issue of Communities of Practice (CoPs). Are they dead, are they at the end of their life cycle, will Social Computing Tools replace them, are they something so fundamental they will continue regardless. Does anyone know of any published, or about to be published work about trends in the development of CoPs.

All help appreciated. Ideally by commenting to this post, or my email if you want to be private.
