Hi Alex -

Getting this type of information would certainly be helpful.
Unfortunately, I'm not sure how to ascertain how many of AVG's 150 million
Users have their Do Not Track feature (enabled by default) or how many of
SiteCom's users have DNT enabled by default. The myriad plug-ins and other
offerings that enact DNT are also difficult to determine. And then there's

Moreover, It seems unlikely that the initial browser enactments of DNT
would meet the requirements of either of the two proposals under

I think the point that many of us are making is this: given how easy (8
lines of code?) it is to send a DNT header, and given the number of
entities that are already sending DNT signals that would not meet either
of the current specification documents, it seems reasonable to envision
others sending invalid (pursuant to the spec) signals once the last call
document is published.
