If you had the massive user feedback that these social news sites get, could you use that feedback to improve the Google News ranking calculation?

It would be an additional type of signal. We offer a "most popular" section on the front page of many of our editions. That popularity ranking signal is different from how the front page is ranked, which tries to reflect what editors are publishing on their sites. If we introduced a Digg-style feature, it would be more similar to that popularity metric. Today, we're still trying to reflect what editors are doing because that's an important purpose Google News has served: to reflect aggregate editorial interests in a story.

What are the advantages of using Google News versus Digg or Slashdot?

Comprehensiveness is a huge piece. If you want to know if someone in the news space is writing about a subject, you do a search on Google News. If you want to monitor that on an ongoing basis, you set up a Google News alert.

Some critics say that the ranking algorithms of Google News don't take into consideration story quality or who broke it.

This is why we're out there talking with editors, because we hear these things from them, the ways in which we need to improve the algorithms. In an ideal world, Google News would show you who broke the story and the other articles that built on that. There are places where we're not doing that perfectly today.

How much outreach do you do to talk to editors in the publications you index?

It's something we're looking to always do more of. Our ability to reach out in various regions of the world has dramatically improved in recent years. We go to [media] conferences and do tours of regions. But it's hard to reach out to everyone individually, which is why we do a lot of online support so that any editor with a concern, suggestion, question or comment can share it with us.

Do you pay any of the news outlets you index in Google News?

We very much believe that what we do with Google News is fair use. When someone disagrees with that, we're happy to talk to them and work with them to make sure their content is opted-out of the product.

We believe there is value in Google's search services in the traffic that we give back and that most publishers want to participate. When we want to do things with content producers that go beyond that [fair use] of linking back and giving traffic back, whether it's a maps producer or a satellite imagery provider, or even some of the video publishers, then we enter into contractual relationships that may involve money for content.

Any plans to run ads in Google News?

We're focused on improving the quality of the product. Some of the issues that you threw out earlier are higher on our list of things to tackle, so that's where our focus is.
