- What are the specifics of the mechanism by which they ended up obviously copying google's results? They said is was user click stream data. User types search into Google, gets results back and clicks link. Microsoft gets sent the search term and link clicked.

- Do they handle clicks from google differently than any other clicks? Hopefully they do if they are using user clickstream data. Each domain should have something like a page rank to determine how trustworthy it is.

- How different would their results be if they didn't use clicks from google's search as a signal? Why would they not use Google. Google is a site on the internet where users click links, Microsoft is collecting data from sites on the internet where users click links.
