So what happens when you shoulder surf your team and they're reading reddit or hackernews? lol The funny thing is I work in an open place and really don't care if people see me reading reddit or hn or whatever else on my screen and I happen to not be focused on a task. That said, I got startled when a tour group walked by and closed my browser one day. That was weird.
