I See You

    There's an odd trend happening in social networking: Showing people whether or not you've seen what they've posted, breaking the tacit agreement that nobody ever knew what you looked at Facebook. Now it's like they're looking back at you. This is how Path works; it's how messaging services like iMessage and Facebook Messenger work; and now it's how Facebook Groups works. You have to wonder where else Facebook will be rendering your gaze visible.
