Wither Passport?

Microsoft hasn’t talked much about Passport lately, but Monster.com sent out an email last week saying that they were discontinuing the option to sign in using Passport. And I noticed today that eBay isn’t offering the option to sign in with Passport anymore either. Although the creepy Passport for Kids site is still up and running, and the notice from last March about the Express Purchase service getting killed is still up, but I think the definitive bad sign is that the directory of sites using Passport is gone.

Was there some press release from Microsoft about Passport dying? Did I miss it?
