"Going forward, posts can either be private or public. Private posts can only be seen by you (and for the time being, appear under drafts in your private view). Public posts can be seen by anyone.
This change will pave the way for additional sharing features launching in the coming months. You'll be able to selectively share private posts with other people on Kinja. You'll also be able to allow those people to collaboratively edit [bp: why?] those posts."
