It would be nice if we could deny support for terribly non-compliant browsers. The problem is, denying IE support hurts your site, hurts your prospective users, but doesn't hurt IE. That's note exactly what we're going for. I propose a different technique. What if all anti-IE developers put a "Please stop using your crappy browser" splash screen for all IE(6) users accessing their web site. They could provide a few good, simple reasons to switch, that the user can't ignore, but then allow the user to access the (IE compliant) site. That way they could get the point across, without hurting themselves (much), or the user (except a little).
