I have been thinking about making an extension that shows you how long you've wasted today. Whenever you visit a time-wasting site there would be banner ticking away.

It's not exactly the same thing, but Rescue Time is awesome for this (especially when you get the reports about your wasted time).

Statistics are actually a planned feature. I decided to ship before I made it. It's going to happen at some point :P
