Nettiquette

I've been arguing with people on facebook a lot these days, and in general, I like to scour comments on articles and blogs to get a gauge of public opinion. I come to the conclusion that while many people communicate pretty well, many other people equate flaming with debate, and they can't seem to figure out why other people get offended. I think that soon, schools are going to have to teach kids how to communicate in forums and over email just as they teach them how to write letters and essays.
