I'm not sure they're floating trade ideas on message boards, but somebody in the PR office certainly keeps an eye on twitter, social media, etc. That even came up in one of the recent articles linked on the front page of TBD, about how the PR folks monitor twitter to see what kinds of rumors are floating out there (and what players are saying). I doubt Buddy Nix or Russ Brandon are personally checking out what we have to say, but some young flackeys/interns almost certainly are.
