Twitter reproduces 99.8% of George Orwell's novel 1984 (scrivna.com)

If by reproduces you mean 99.8% of individual words in the novel could be found independently in tweets - the Oxford English Dictionary could reproduce most of Orwell's novel too if all you need is each word to have been used somewhere.

This could be much more interesting if it was considered a look at words falling out of common use, or to compare the literacy levels of different sites etc.
