Hi Nick,
I am sorry to have missed your session today (was at the dentist) but am catching up. Thanks for these 3 links - some very nice work here. I especially like the networking and the potential of using a suite of tools and technologies to allow a person to engage in a constellation of communities of practice depending on their needs, requirements and context of their efforts. There are lots of options and yet flexibility for participants/members etc.
thanks again,
Barb
