The bottom right of that flowchart is a little scary. So anything you post, no matter how private you want it to be, can be seen by anyone that it gets re-shared to?
Nevermind: just noticed that that only applies to posts you share publically.
wrong.. if you mark it as a limited share...no one outside that circle can share it..try it yourself and see...it is a new change that went into effect over the weekend
That's a good change, but that's not my point. My point is that things don't automatically become unprivate because there's a share button. Somebody has to make the decision to share these things, and they still have the ability to do so without a convenient button. The point is that users should still maintain good sense about what they post.
