How does doubleclick have demographic data for HN? I would love to be able to see how doublieclick defines me demographically.

  Presuming it is the same as Google Ads: https://www.google.com/settings/u/0/ads/onweb/ https://www.google.com/settings/u/0/ads/onweb/

    Doubleclick is a part of Google.

  They have tracking cookies installed on most user's machines. This is because they have such a high penetration rate of advertising inventory which they use to profile you by age /sex / interests. Then it's just a case of marking you as an HN user, they do this by detecting the referrer when you arrive at one of their sites.
