That's generally how long I need to break an addiction
I'm sorry, but 10 minutes on a saturday morning does nothing for me.
Happy to have been of assistance; please send the $250 to GiveWell. ;-)
It lets you limit the number of minutes you can read sites (and importantly links from thoses sites). I give myself 10 minutes per day until 9pm at night.
I would have thought getting to the root cause of your “HN addiction” would probably be a better alternative.
