This perhaps isn't the venue to preach standards-compliance, but it is worth remembering that directory editors (and it's not just the ODP editorial community -- Yahoo has historically been particular on this also) is less Microsoft-centric than, um, your average computer user with a new computer from Staples and fresh bruises from the turnip truck. I personally won't list a site I can't view with a reasonably-standards-conforming browser (and the Infernal Exploder doesn't come close to qualifying). 95% of your target audience may be IE-victims, but 30-50% of your reviewers are NOT.
As I said, this isn't the place for a crusade, or even a debate. (Not that you could change my mind: I have 20 years experience dealing with standards, from both the implementor and from the user side. This is a religious issue. I've tried it both ways, and portability is GOOD; undocumented features and noncompliance are EVIL.) Webmasters need to be aware of this.
You can take your choice--code for everybody, or leave all your work hostage to Bill Gates' good intentions. But if you do decide to be a Gates pawn, at least mention the fact on the splash page. "This website generated by the spawn of hell, and cannot be viewed by a browser compliant with WCC recommendations." Then I won't accidentally delete the submission thinking it's just broken, and some other less-IE-phobic editor will eventually review it.
