Not sure if I completely believe the quote. To me, it’s someone in packaging that got a little carried away when talking to advertisers:
What most users don’t know is that the new features being introduced are all centered around increasing the value of Facebook to advertisers, to the point where Facebook representatives have been selling the idea that Timeline is actually about re-conceptualizing users around their consumer preferences, or as they put it, “brands are now an essential part of people’s identities.”
