homepage turns up 322 markup errors but only 22 css2.1 errors, but the site's almost completely unusable for me
As a webdeveloper I'd discovered long ago that if I develop primarily with Opera first, and then test in IE/FF/Chrome later, I wind up with far fewer cross-browser (in all browsers, not just opera) bugs to fix overall, which saves me gobs of time.
Just a thought but seriously the site's almost unusable for me in its present state (and I've always used Opera here).. this is actually the worst I've ever seen it, and I've no idea how it managed to break so horribly.
