Clarifying questions:

Does this mean a 3rd party can collect and build a profile about my activity on a 1st party site, but cannot correlate it with data collected on another 1st party site?  Example: Adserve.com could collect data about my visit to News1.com and serve ads to me based on what I did on News1.com? Adserve.com could collect data about my visit to News2.com and serve ads there based on my News2.com activity, but could not combine those two profiles?
