I’ve been trying to get the trackbacks and feedbacks separated from the main comments. Unfortunately, every trick I’ve been able to dredge up on the web has been a dead end, and some of them temporarily broke the comments. I finally decided to make trackbacks and pingbacks just a little more noticeable.
I’ve also upgraded to 2.2.1, which necessitated a re-hack of my feed-generating files. Those went off-line for a bit, but they’re back.
Sorry about that.
