In May, my colleague Sarah Jacobsson Purewal noted apps. She said these types of features create a "giant circle of awkward oversharing that people have little control over." Who knows--what you're reading might reveal things about yourself that you're not necessarily willing to share with the world.

Since there's no way to control what type of content is shared, except to not share or like it altogether, your personal reading habits will be on display for all your friends. The only positive here is hat, unlike Social Reader, you physically need to take action on Facebook--whether you share or like the story--for it to show up in the Recommendations Bar.
