The lengths that people will go to to refute 0.99.. = 1 are truly astonding.
A poor math teacher wrote the proof on his blog, Polymathematics, and got linked from all over the place, including digg and reddit. Digg went so far as to bury the link to his proof because so many of its users wouldn’t believe it, thus proving that democracy doesn’t work.
Polymath does a good job to address the common refutations in a subsequent post.
