This may surprise you, but I haven't actually written anything new since September. Everything that's been released was already written. The problem is that time is short - I'm just too busy. I know that I oscillate on this topic as the years go by, but right now I'm in a funk.
The plan is to release episodes through 900 (actually, 900 would come out on Friday 11/25 according to the current schedule) and then take off the rest of 2005, with the idea that I'll release 901 on the first Friday of 2006 and then go from there.
