Illiterate People

I hate it when people try to communicate on the Internet, or through any other written medium for that matter, and completely make fools of themselves by typing a bunch of nonsense that takes forever to even read, much less comprehend. Nobody takes you seriously when you communicate like a three year old. I mean, a basic grade school education is mandatory in the United States, last time I checked. Why is it so hard to spell or use proper grammar?
