The Serpent's Skull game that I'm in (and its Discussion thread) have both finally shown new updates! They used to only show updates in FeedDemon if I deleted and re-added them. (I follow quite a few other games, including a couple more that I'm in, with no such problem.) I really hope that this isn't just a one-time thing caused by some kind of reboot, since I find RSS to be a handy backup to the campaign tracker.
Edit: Oh! I just got an update in FeedDemon of my latest post! That's never happened in that thread before. Something has definitely been fixed. 8)
