Happy anniversary, guys!
Change is bad (said the change management and training consultant). I have enough podcasts of dudes just chatting about movies and TV for 30 to 60 minutes a week. But I look forward to whatever you decide to do from week to week. 
I probably have a substantially higher tolerance for delays between releases, so I'd be happy if DIF did 1 commentary a month. I think other commentators I've greatly enjoyed have burned themselves out trying to be too regular. I've been amazed that DIF has soldiered on so regularly for so long.
However, regarding the community collapsing—I do retain the fondest memories of the Blackadder message board, circa 1996-97, where I'd see 80 or more messages a day from people who shared the same wry sense of humor, and the recursion and cunning plans were the stuff of legend. I wish that stuff was archived....

*PS—ALL those negative comments on iTunes are just me pranking you.
