Interesting. I am trying to remove my presense from FB but years of use and my own laziness is making it difficult. I might leave it as is, just with little info as possible.
People seem upset that FB would be sharing or selling their information. Let me be as plain as I can here. Nobody starts a social media site without getting any money. Clicks and likes are important. Zuckerberg and friends match you up with products and services. They hope you buy them and you get contacted. I'm not so sure I see the problem. I was not naive so I'm not really angry with Facebook.
