Two post that particularly caught my eye were responses from comScore to questions by Eric Peterson about their methodology and the promise they will be releasing more information soon and Marshall Sponder’s post where he looks at what reducing the measured Visitor numbers by a factor of 2.5 could mean to the numbers published by some of the bigger online retail sites.

Are first party cookies just as likely to be rejected as 3rd? I also wonder where the IAB Cookie Management Taskforce is with their research. If comScore used only one publisher, I hope it was Yahoo!
