I only tune 200 as a matter of habit, and in case there might be someone in another country I might actually want to talk to. For the most part I find the pitiful attempts at "smack talk", as well as the "I don't like the way you shot me down so you suck" purse fights, to be more and more annoying. As it stands, I can ignore it, but then I don't fly that much any more, so maybe that's why I haven't tuned 200 out. Yet.
