typing in caps

I really can’t believe that I’m writing this in the year 2008 but when you type in all caps, you look like a rude child. Perhaps you’re trying to be emphatic but the result is a dizzying mess akin to shouting. The reason for typing in upper and lowercase is not simply for the sake of netiquette but because that’s the best visual way for letters to be understood as words.

I just had a client send me an email typed in all caps and it’s like trying to decipher a baby’s screams. When every word — and in fact, every letter — of every word has the same weight, I can’t focus on the meaning of the email.
