[Air-L] question about use of Facebook in classroom

[danah boyd]

Nancy - you've deleted them from your public profile, but it's still  
stored in your account.  It has to be due to COPPA.  Ads are delivered  
based on back-end information, not front-end information.  Thus, when  
Company X buys adds from Facebook, they tell them to just deliver said  
ads to people over 40.  Then, when Facebook generates your page, it'll  
ship you an ad, regardless of what info is public on your page.   
Facebook makes it a pain in the ass to change your birthday, but if  
you set up other accounts with different birthdays, you can see the  
span of ads generated.  (Yes, I'm a dork.)
