If it wasn't readily apparent how little you "got it" before this post, saying "We just don't work hard enough" destroys any credibility you may have here.

Sorry, but there's a difference between "working hard" to make sure your site looks good and functions across as many browsers as you can, and wasting hours of your valuable time that could be better spent elsewhere, trying to get older versions of IE to show things properly without damaging all the other browsers.
