Seems I have missed the great debate: what is the purpose of 'Utopia' as a concept or a real place. For latecomers to the debate, Matt_c over at Fisking Central has a good overview with links to some recent comments on utopia. And although Norm takes a different view, his own take provides a useful framework for thinking through how to deal with the concept.
Still, let me take nothing away from Matt_c's piece, which is a very enjoyable read, not least for his recognising his (temporary?) channeling of Richard Dawkins-esque ranting!
