15 in 30 Update
Well, I seem to have failed to consider something: My regular case of post-Christmas blues. The combination of daylight hours of shorter duration than your average sneeze and the departure after an all-too-brief visit by my children always puts me into a funk that can last for days... and which isn't particularly conducive to being funny.
So while I still have 4 more days, I have 5 essays to write in that time, and I'm not sure I'm going to make it.
I'll try to pick up the slack, but we may end up with only 11 or 12 in 30 days.
