How collective is your revolution?

From an e-mail I wrote discussing the theme of the debate in Futuresonic late this week:
"One question that we have been coming across is that in Brasil social networks are everywhere: everyone is a crossroads of layers and layers of networks. That has good and bad consequences, in the sense that there are always opportunities (and possible social mobility), but also an uncertainty (informality leading to very flexible application of laws, networked crime, etc). So, when it comes to technology, and using technology to support social change, how do we deal with that, how can we influence the appropriation of technology with the 'good' side of networking, while assuring it won't become just another source of distributed violence."
