I was at ProductTank in London last night. As is often the case, my post-talk discussion with other delegates over beer rapidly descended into farce. We ended up talking about Facebook’s Timeline, which everyone’s been forced to adopt, and how Facebook and Twitter differ from Google in terms of what they know and what they infer about you. It was at this point that we came to the realisation that Facebook was essentially playing an elaborate version of the drinking game of “I Have Never…”. All is explained after the break.
