I support what John and Jeffrey said for 2 reasons

1. User expectations:
	Of course, it is difficult considering user expectations without having 
actually done comprehensive user studies. But as Jeffrey pointed out, 
from my experience it is not too farfetched to say that most users do 
not know or comprehend how and when data collection occurs online.

	If the majority of the Working Group decides on not addressing first 
party tracking, we need to think about our definition of "cross-site". 
The Yahoo! example shows quite nicely that it gets more and more 
complicated for the average user to identify which services or sites 
belong to the same corporation. Flickr clearly states in the title of 
the website that it is a Yahoo! service. Nevertheless, I would not be 
surprised if a significant number of users just overlooks this 
information and would be surprised by being tracked from Flickr to 
Yahoo!Chat while having DNT on. And there are a lot of services that 
make their "branding" not as clear as Flickr.

2. European regulation:
	If you agree on not including first party tracking, you decide to not 
address in which way soever the requirements of Art. 5 III of the 
E-Privacy Directive concerning first parties. Lost opportunity.

Best regards,

p.s. Sorry, I am travelling and will not be able to make it for the 
weekly call today.
