We are seeing very high tweeting coming from Hackney as another day of rioting takes place in London. It is pretty clear that like the Arab Spring rioting and violence in London are being planned on social networks. We are seeing a score of 95 which we only generally see in the center of London or Amsterdam.
You can open twitter and see descriptions about how the rioting in being planned and carried out. So social networks prove a old idea about technology in general, that technology does not have a innate good or bad influence, people give to technology a moral or immoral use. In London the vast network of twitter and other social network users is enabling a small and highly violent group of youths to act out in an anti-social way.
