One thing I really like about Google+ is the ability to limit your posts to a "Circle" of people. Facebook recently added a similar feature. I decided to try it out and share a post with all my roller derby friends (including my wife). So I start exploring the UI and hit this:
I had no idea what to put in the "Hide this from" text box. Maybe "everybody else"? Turns out, you can ignore it, and it'll be limited to just that single list. I assume that box is so that you can add a list and then exclude someone. Please to hide that away, or even take away the feature entirely.
