FOLLOW UP ON INTERMITTENT NEWS AGGREGATOR

I’m subscribed to 103 news sources using Radio’s news aggregator. It’s a primary way for me to keep up with weblogs and sites that fit my interests. I had reported that I thought I was seeing intermittent performance. Specifically, sites are getting updated, but they don’t show up in my news aggregator.
Here are three sites I know for certain have updated in the last few days, but they never came through my news aggregator:

• Dollar Short
  
• Diveintomark
  
• Blurbomat

The coincidence here is that all of these are Movable Type sites. Does anyone have any clues about what could be happening? AP NEWS HEADLINES on the other hand come through my aggregator multiple times with each refresh!
