RescueTime

Overview

RescueTime isn't strictly a distraction blocker, but it does contain a "Get Focused" mode which can be used to block all sites that you find distracting.

The real power comes from the in-depth tracking statistics. You can easily find what's distracting you the most after using it for just a day, and then adjust your habits accordingly.
