<i>Facebook, on the other hand, does not make an effort to warn people the they’ve been tagged (possibly in an unflattering or compromising photo) and give them an immediate chance to remove the tag.</i><p>What? It definitely does. I get an email every time someone adds a picture of me. I also think a lot of us make an effort not to delete unflattering photos. Not every picture posted is nice, but it adds new dimensions to your online personality. If you don't like people adding your pictures, you can always change your privacy settings.<p>Most of these reasons other than data liberation are very one-sided. Facial recognition can be seen as a bad thing, but some would argue it's a nice feature. Although, honestly, what information on my Facebook would I want to liberate anyway? My years-old wall posts of "Omg I miss you" and "lol up!!!" that I never even look at?
