An excellent post from Kathy Sierra on this subject. It has been one that has given me the yips for some time. I have enormous problems with the idea of striving towards excellence by adopting the behaviours of swarming creatures (in spite of the fact that I admire their accomplishments). I also have problems discerning any wisdom in the behaviour of crowds at soccer matches. It's good to see someone with Kathy's credibility putting it into perspective.
