If you just have the mindset that anything you share on facebook will be posted on a billboard in Times Square, you can know for sure that you are getting the privacy you want.
The perception is that when you gave that information over to the entity it will stick with the privacy rules you had setup at the time. In this case, Facebook's new systems are ignoring those privacy settings and making things public that were previously set to be private. At the very least, they are adding new features that give new views into your data that make your existing data public.
What I don't get is, why doesn't somebody just build an alternative to facebook which treats your data as private and not public. Then you could have the people still on facebook install an app to allow the secure-book people (or whatever) interact with their data so everybody can be friends across platforms. And maybe another app for vice-versa usage. bada bing bada boom.
Not really...
In other news, that tool he made (http://zesty.ca/facebook/) is pretty neat.
I hesitated to rely on "security through obscurity" when using FB events as well as the old "fan pages", but social pressure caused me to give in on a few occasions.
Guess if and as I remain on FB, I'll avoid anything that has a public aspect to it.
