Last week at the Search Engine Strategies conference held in San Francisco, Matt Cutts did a keynote address. After the keynote, there was some time to personally discuss a few issues out in the hallway.
Here on WebmasterWorld there have been some discussions regarding the data that Google is collecting via their Chrome browser. There have been some rumors and even a recent presentation from a former Googler that said that clicks on links from Google Chrome were more powerful than other links--because Google could measure that those clicks. (I can't find the exact URLs of those threads right now though.)
I personally asked Matt Cutts about the use of Google Chrome data in the the Google organic algorithm.
We can now put this all to rest. Matt told me, in person, that Google's organic algorithm does not use any Google Chrome data. The same goes for the Google Toobar, as well.
