I just saw an inteserting article on slashdot (yeah, I at least chcek the headlines from time to time) about how charcater oredr in English words doesn't matter as lnog as the first and last characters are the same. You can still read it because you don't read every character in a word. Presumably you rely more on context than spelling.
Yes, that last paragraph was a little demo. I guess a guy by the name of Jamie Zawinski wrote a little Perl script here that scrambles words for you. Anyway, I thought it was kinda cool.
