I saw signs of this around 9am EDT this morning but didn't see enough chatter to cover it yet. I suspect over the weekend the forums will light up. Some of the early stats I saw on sites that got hit were huge.
Of course it was a late Friday release:
I'll have more details on this on Monday, with the impact on real webmasters.
