JagsLive sends in a Washington Post blog post reflecting on one privacy-enhancing feature of the upcoming Internet Explorer 8, the so-called "InPrivate Blocking" that has privacy advocates quietly cheering, and advertisers seriously worrying. Here is Microsoft's description of the feature. From the Post: "The advertising industry is bracing for trouble from the next version of Microsoft's Internet Explorer, details of which were announced today, because it will offer a feature that blocks some ads and other content from third-parties that shows up on Web pages. A Microsoft spokesman said that the feature, to be known as 'InPrivate Blocking,' was never designed to be an ad blocker, though 'there may be ads that get blocked.' Instead, it was designed to stop tracking 'pixels' or pieces of code that could allow third-party sites to track users as they move around the Web."
