I'm ctrl+F-ing through the XML file and I'm still not seeing new nad comments. For example, the comment you posted above ("New comments should") isn't in there. In fact, while the main articles appear in the Market-Ticker-Nad feed, they're not in Everything either (ex. the word "Delenda" in nowhere in the file), whereas articles from the Market-Ticker feed are.

It's not a huge deal. The Everything feed only seems to work for a brief period every month anyway, during which it'll suddenly return 400+ results, then for the next few days it'll work normally until it's flagged as unavailable again for another month or so. That could just be a problem with my ancient feed reader, though none of the other Market Ticker feeds give me trouble.
