A very interesting and insightful post by John Foreman on the Facebook controversy. This passage was particularly poignant, in a post filled with them:
"If I have a bunch of unique people, and I need to target them, I need a bunch of unique content to make that effective. Is there another way?
Rather than tailor marketing content to a user's unique emotional make-up, Facebook has shown that they can use tangentially related (and free!) user-generated content to push a user toward marketing content generated for a more general emotional state: insecure, hungry, lonely, etc. They can edit together photos and posts in a stream to skew a user's view of reality and shift them into one of these compromised emotional states.
In other words, if they can't use data to generate enough personalized content to target people, maybe they can use data to generate vanilla people within a smaller set of emotional states. Once you have a set of vanilla people, then your American Apparel ads will work on them without customization."
This post is a very important one to read. And understand.
