I&#x27;m just amazed at how happy and ignorant people seem to be about giving away Facebook more and more signals about their likes&#x2F;dislikes<p>They started the profile badges thing and folks thought that was so cool.<p>I had to explain to them that this is one more data point for Facebook - if I change my profile badge to a Manchester United logo, it probably means that I really, really care about Manchester United.<p>I can then be targeted by an advertiser that wants to sell merchandise to Manchester United fans
