DEAR EVERYONE WHO OVERUSES CAPITAL LETTERS,
IT SOUNDS LIKE YOU'RE YELLING.
Don't you think that a writer sounds calmer when you write with the correct capitalization? And maybe to emphasize a word, you could put asterisks around it (at least that's what *I* do) or, better yet, reword your sentence. That's how I would change the e-world. And for what it's worth, from a typographical viewpoint, it's really hard to read all caps.
If I could change the real world, it would explode. But at least then all the little things that drive me nuts would go away.
