I hope this is the right place to put this. I just noticed that I havent seen Penny-Arcade in my RSS in some time. Since December 17th to be exact.
And looking at the RSS button from the main site, it seems like its not just me. The "Current Feed Content" ends at Dec 17 also.
Anyways, I hope this helps. And sorry if you already knew about it and feel like I'm wasting your time or something.
