Doesn't that pretty much say it all?
Most opinions, however, don't really need to be written down at all. They can be replaced by a sound effect - the audible equivalent of an internet frowny-face. Imagine a sort of world-weary harrumph accompanied by the faintest glimmer of a self-satisfied sneer. That's 90% of all human opinion on everything, right there. Internet debates would be far more efficient if everyone just sat at their keyboards hitting the "harrumph" key over and over again. A herd of people mooing their heads off. Welcome to 2007.
