>The nefarious bit is in IE- which, although it pretends to allow you to "instruct the browser not to accept 3rd party cookies, full stop," actually accepts third party cookies from any site with a P3P code it doesn't understand.

No, if you select that option, it actually blocks all third party cookies.

No, it actually doesn't (or this discussion wouldn't be happening).

So do you work at Google or are you just a fanboy? IE is not being nefarious in this case. IE is following a standard that Google is actively abusing. Not sure why you have such an infatuation with Google, but I dare say: Everything in moderation.

Could you please avoid personal attacks? They add nothing to your argument while making the discussion less pleasant and civil.

I don't mean to single you out, but I've just been seeing too many of them lately.
