It was good to see all the positivity around the brief dump of snow that we had on Monday. It seems that most of London took the hint (no buses, tubes, trains, planes, taxis etc) and took the day off. People were out and about, interacting with strangers and, heaven forbid, talking to each other. Twitter is gaining traction rapidly as an emergent social phenomena and I was really interested in the tweets/map mashups that sprung up overnight. Twitter is still pretty immature but it's got great potential as a lightweight and intelligently networked social information system. It made the BBC Weather forecasts look lumbering in comparison, being able to see pictures from all over the UK was great. The inherent sociability of a big shared event was brought to life by a relatively simple (but extremely smart) use of technology. Our national obsession with talking about the weather will never be the same again.
