It's funny - yesterday, I removed all the groups I had been
  heavily involved with for 9 months on the same topic.
  [philosophy/logic] because, well, I realized I've gotten all I
  could out it and was about to start going around in circles.

  Today? while part of me wants to go back, I have VERY LITTLE
  otherwise on my feed, and I'm actually able to _focus_ better
  now. It's SOOO quiet. Not that I didn't enjoy myself for 9
  months; 'cause I did, but it's a kind of freedom to actually let
  something go when you realize you're done.
