 Two things aren't working as I'd expect:
 
 1. `expirecount` doesn't take effect on the first run, but on the second. (This is minor, just a bit confusing at first.)
+
+> 
+
 2. Where are the article bodies for e.g. David's and Nathan's blogs? The bodies aren't showing up in the `._aggregated` files for those feeds, but the bodies for my own blog do, which explains the planet problem, but I don't understand the underlying aggregation problem. (Those feeds include article bodies, and show up normally in my usual feed reader rss2email.) How can I debug this further?
