We completely agree that privacy features need some significant enhancement, not just at Tribe but across all social networks. People have been discovering, and continue to discover occasionally to their dismay, that they the things they post on line are discoverable by just about anyone.

Tribe's existing privacy controls are about as good as the rest of the industry - private tribes and "friends only" is pretty much the industry standard now, if not slightly better. But it still leaves a lot to be desired and we have plans for a pretty ambitious privacy system.

It will always be a good idea to think about what you post. Posts on a website or even email are a bit like Tattoos: better not to do while drunk or in a rush because chances are you're going to have to live with it forever.

Even comprehensive privacy controls will not prevent someone who does have access from either unthinkingly or intentionally making private information public, but it will be easier to control who is trusted with that risk through much more flexible access control.
