Hi everyone, at the GAIA meeting last week we chatted a bit about the "first" community networks.
Armin Medosch wrote a bit about them on the "The Rise of Network Commons"
http://thenextlayer.org/ The site is down now, but yesterday was up, so I guess they will solve it soon.
Marco Zennaro also mentioned a network in Denmark an some events around it that for him set somehow the beginning of the movement. Some links below. Apparently, the network is no longer operational, so it would interesting to understand what happened for such a seminal work to stop operating.
