I am surprised that this slashdotted article about fonts that are hard to read and learning. All people who learnt a human language based on another writing script already know that and it's already well known the brain captures text faster than your eyes can see them if the font it uses is part of your own "native script basket". When I started learning yiddish, I had to learn the hebrew script. Took time, and concentrating on the characters obviously helped me concentrating on the words and the sentence. I hit the same wall again when I read a yiddish text using a fancy font I'm not used to: it's harder, slower and the result becomes sharper.

Given the example the article uses, I hope all school manuals won't switch to Comic Sans...
