The procrastination point is quite an obvious one. By way of cutting down on my HN time (as I don't play WoW), I've started using the pomodoro technique (http://www.pomodorotechnique.com/) to keep me focused on one thing at a time. So far it seems to be working quite well and I'm cutting down on my distractions.

What do other HN'ers use here to cut down on distractions and interruptions?
