"The new “Post Feed Redirect” will occasionally stop redirecting clients when it is set to a FeedBurner feed. The workaround for now is to add an “?alt=atom” parameter to the feed URL in your FeedBurner settings." (Known Issues, 7/31/07)
I went back through all of my blogs, added this fix to each site feed, and now will wonder about another shift in the subscriber statistics displayed.

Taking a short break from shelf-shifting I worked a bit with the feedburner headline animator. The case of the magical missing post clip art, it's here - it's gone, is because I wanted to try my own background on the headliner; it didn't like the photo I loaded. I deleted the clip art and decided the headline animator was not necessary here. Play to work.
