I have to admit, I'm interested. It almost looks like it would work. Maybe too much like Thing is your nanny, though.
When working in a medium sized office setting, you tend to share links with your co-workers, and then forget to show your other friends. This is a demonstration of what a recent study claims we spend 25% of our office time doing (while maintaining or even increasing productivity). Our managers, on the other hand, would call them "distractions".
