Other than "Ask Chad", and starting the episode threads, I don't think they've ever been much more than lurkers. Does seem odd how they went from talking up the forum to talking up the *name-your-trendy-service-here*, but we've still got a nice place to chat, and new folks are dropping by regularly.
Personally, not so sure about the "community" over on FB, though. They post and then a stream of likes and comments appear. Maybe I don't have the patience to wade though dozens of "cool post" comments. For all I know, there might be good back-and-forth in that . . .
(to weakly claim on-topic) Good for you guys! I know the airshow episodes don't get the ratings, but they get some of the neatest (no pun intended) interviews! These fly-ins are also one of the best things we do in this hobby -- hang out, show off, and fly! Perfect place for youse guys to start some awesome ideas for future shows!
