Audience Reporting Sites

[SuperDave2U]

I use Quantcast on almost every research project I run and have found to to be extrememly helpful with targeting. Do any of the big time guys use sites similar to this they can recommend ?

Anyone not using it already, check these out:

acaiberryjuice.org : Quantcast Audience Profile
acaiberryjuice.org : Demographics Profile

Quantcast is great for target research, I don't know of any others though.

Do you know if they make all publisher data public? Or is there an option to keep your info private?
