Memes show a picture's worth 1000, yeah. that one.
  I prefer animated gifs myself and Vines - TOTALLY hooked on
  those 6.8 second things. Making them, not consuming them. Made
  like 12,000 so far.

  I may be GenX but I grew up on the 'net and have had plenty of
  meme-only conversations without a single word used smile
  emoticon I've also had entire conversations in pseudo-code back
  in the days of Usenet. Fun stuff.

  Actually pseudo-code would work well for analytical
  philosophical discussions.

  Or line drawings. Little machinary showing the logical
  progressions. Even though I'm not an engineer, this would be a
  suitable form of discussion for analytical philosophy. It's not
  hard to read.
