I just assumed it was the disgruntled, ex-DL flyers who have moved on to other forums!! Seriously, there seems to be a lot of angst among the more vocal Flyertalkers. Perhaps Flyertalk is really some barometer of business traveler stress...As someone who lurks for deals and makes a few contributions here and there, there is a clique-ish atmosphere... but not radically different from other (focussed) message boards.
