The Internet is a lowest common denominator medium. Unlike newspapers, books, and magazines, there's no editorial staff, no advertisers to please, and no style guides, standards, or traditions to uphold. It's a Tower of Babel mishmash filled with junk. On the Internet, nobody knows you're a dog, a 15 year old pimple-faced kid, or just an idiot. Why does this matter? Because one person's opinions are not just as valid as another's, if that other has absolutely no background, skill, or expertise in the area he's commenting on. Yet it's become a staple of many otherwise reputable print publications to let just anyone comment in their "blog" or message board about editorial content.
