Gotta be so careful with the likes and what you talk about and
   respond to, lest the feed gets cluttered. tongue emoticon I had
   to teach a young person who was ready to leave facebook over the
   depressing stuff on his feed how it all works and how to
   customize his feed. It worked, and he's happy now with more
   positive vibe feeds showing up. FB responds quickly when you
   treat it right.
