One other interesting side effect of FB's aggressive stance on these features that I haven't seen discussed elsewhere is that it makes it progressively harder to be an inactive member. I know many people who have created profiles which they feel obliged to keep (to maintain communication with certain family members, friends or colleagues) but are otherwise not terribly interested in it. FB is subtly adding a form of reputational decay to your profile. If you want your profile to represent you in a non-embarrassing way the next time a friend or colleague looks you up, you now need to log in much more regularly to un-tag yourself from photos and remove yourself from inappropriate groups (on top of figuring out whatever the latest changes are to your privacy settings...) Fun!
