What is to keep an organized attack on a site's display method in IE8 by overuse of the 'compatibility mode' button when it's not appropriate? Especially since tech-un-savvy users will then see a site in compatibility mode when they didn't do anything in their browser, and they'll assume the site is busted? Also, at which point do we stop assuming the majority of users are not tech-savvy? How much longer do they have to catch up? Everyone knows which hole the food goes in, no one makes special easy-to-eat food for the food-un-savvy crowd.
