But it does have a wealth of useful data! It has the social graphs of a lot of people, it has a somewhat meaningful list of things they are interested in, and it has a bunch of photos of them. Those things tell stories all of their own, regardless of how shit facebook is.

I'm not sure if you are being sarcastic or not.

I'm not. Facebook has a massive store of data that will likely be very interesting to future historians. Just because it is biased and unreliable doesn't mean it isn't useful.

I'm concerned about future powers using data to target me and my family for "re-education camps"

Perhaps foolishly optimistic, but maybe they can turn things around. They abused a lot of people's trust, but it isn't impossible to imagine they could win it back.

It's possible, but OTOH how many sites have lost their users and won them back? MySpace, Digg, etc, went down forever, and new users (teenagers) don't seem generally interested in Facebook.
