This generally splendid article is doing the rounds: http://www.guardian.co.uk/technology/2010/feb/04/mapping-open-source-victor-keegan
But much though I might like the kind words for Potlatch's drag'n'drop POIs - and much though others might giggle at NickB's new surname - this is the really important bit:
Gordon Brown, the UK prime minister, has just rediscovered cooperativism as a way of galvanising people to vote Labour. He would have been much more in tune with the times if he had widened it to include the open source movement in all its different aspects. It is one of the most interesting phenomena of our times, a kind of global mutual society.
Absolutely spot on and not something that's written about enough.
