Heh! Nice pie chart!!!!
A lot of web designers seem to totally ignore the KISS (keep it simple, stupid!) principle...
It's not too hard to make sites that degrade gracefully when run on non-CSS browsers, and to carry out more of the processing on the server side rather than the client side when technologies like AJAX aren't available...
But then again, if 99.9% of a web site's audience is running a current version of either Internet Explorer, Firefox or Opera, there's little incentive to make it work with anything else, or to test it under AWeb!
At least the days of the IE-only web sites are numbered, if not completely gone.
