A WebmasterWorld thread cites recent Search Engine Watch story that says that Google's Matt Cutts said his team, formerly known as the Search Quality Team, has been renamed to the Google Knowledge Team.
He said this in his opening keynote a month or so ago at SES San Francisco. He said, quoting from the story, "Google is so committed to this that Google's Search Quality team has been renamed to Google's Knowledge Team."
I have not heard this mentioned elsewhere. It is a name change, not a function change.
Honestly, I'd assume there is a team at Google working on specific things to the knowledge graph so I am surprised the search quality team would take that name and not use that name for the specific team who deals with the knowledge graph?
I was not at the event, so maybe this is being taken out of context or maybe not?
