DOES THIS DRIVE YOU MAD?

I recently read somewhere that distaste/disdain for people who typed in all-caps didn't exist before the popularization of the internet. I don't think I agree. It seems to me that yes, it was more uncommon before the rise of AOL, but it did still occur. I believe I'd have just as much of an aversion to reading a book printed in all-caps as I would an ICQ message posted that way. And I think I wouldn't have wanted to read something like that in the 1980s, before I ever so much as used email.

Do you have any opinions on the matter?
