@boomerang,
Actually, it's all very big business. I've told you this before. You are not the customer at Facebook, you are the product. The customers at Facebook are the advertisers you see. Facebook doesn't actually give a rat's ass if you are comfortable with their policies. What they care about is being able to sell advertising space on a presumption that there are a half billion "subscribers." (Also spelled s-u-c-k-e-r-s.) If you give up even more information or access to that information, all the better--but once you sign up, they've gotten what they wanted.
I'm signed up there just to play games. Zynga is the company which provides the games. Lately, in Farmville, i keep getting these pop-up messages which say "Your feed did not properly post, please click on 'send report' so we can fix this problem." So, i click "not now," because i know they're bullshitting. So a second pop-up immediately appears which reads "OK, you feed posted this time, but our records show that you've had a problem with this in past, so please click on 'send report' so we can fix this problem." Well, it ain't no problem for me. What they want is for me to give them (Zynga) my e-mail address. Since all my feeds post through FB, they don't need it, they just want it. Why would they want it if FB provides all the contact i need for the game?
Not big brother, Boom, big business.
