Aggregator Problems

I am having some problems with the aggregator software. There are numerous posts missing from the aggregator as displayed at I have my old aggregator that I wrote here, and I may simply revive it. It only lacked ordering by posting date and its own RSS feed generator, and I have most of the code for those.

The problem is that all blogspot blogs and a number of feedburner feeds are not updating correctly, which removes most of the blogroll from both the main aggregator page and the RSS feed. I will update you on the progress here over the next couple of days. I apologize for any inconvenience.
