As it turns out, I was wrong about ICANN not updating its RSS feed. It has been updating the RSS feed continuously, but it was ordering the items from oldest to newest. Now, as I understand it, better RSS readers will read the date elements of the feed and sort entries however you specify, but my RSS reader (and those of others, I'm sure) were simply presenting the entries in the order in which they appeared in the feed. This meant that we were seeing the same entries at the top, day after day, while new entries were being added to the bottom where we weren't looking. ICANN has changed the order now (Thanks!) so those of us who were not reading the new items at the bottom of the feed now will get them at the top where we were looking.
