Stayfocused
Amazing tool to stay focused.  It is an extension that works with the Chrome browser and once you activate it, you can block or set timers for any site.   It is handy to ensure you limit yourself to a certain amount of time per day to certain tasks - ie 60 minutes per day on Facebook for example.
