Inventing Favicon.ico
It's positively galling how happy he is about such a terrible decision.How many billions (trillions?) of wasted favicon.ico requests have been made because they didn't bother to engineer this the right way and make it a  tag in the document? And pushing the Windows-specific icon format was just icing on the cake. And now Apple's doing it too with two more of their own requests.I wish we could send him the bill for all the wasted power, all the wasted developer time (even ten seconds per developer for all 100 million+ sites out there adds up to quite a lot.) Then see how glad he was he checked this misfeature in.EDIT: I don't care if you downvote, but if you do so, please tell me why I am wrong. I'd genuinely love to hear why you think this was a good idea.
