It seems we're in for a reversal of the privacy defaults on the web, unless you want to stay off the social media most of the time. Facebook is reversing the default anonymity we're enjoying now. Sure, doubleclick maybe already did that a decade ago, but at least we've had the illusion. That's all gone now.
This means that the content filters that were previously only relevant for walled-in corporations who did not want their frivolous employees to do frivolous non-work suddenly become relevant for all of us.

It's okay to wear a badge as long as we stay in Disneyland, but we'd probably like to take it off when we're passing through the red light district.

I see a great new market here for the filter vendors. Personal reputation management.
