So everyone's been posting links to this paragraph which claims that according to " rscheearch at an Elingsh uinervtisy" the order of letters doesn't matter; as long as the first and last letters are right, people will be able to understand meaning. Someone even wrote a word scrambler that lets you mix up your own paragraph.

However, I haven't been able to find any links to the actual study, or anything more than that first graf, that proves there was actual research done on this. Maybe I'm too suspicious for my own good.
