I've long subscribed to the full feed "The Tao of Mac"[1]. Recently it seems some things have changed in the feed. Now items that are updated are nog longer marked with the changes, but appear as a new unread item (and the old one is still visible in NetNewsWire).
I've tested the same feed in Thunderbird, and it doesn't appear there.
I've examined diffs of the feed source, and the only thing that appears to change are minor corrections to tags, and references to googleadservices are removed from the item after a couple of days.
This is incredibly annoying, because it means that if I regularly fetch his feed, and he makes several tiny changes, I get a new item for every change he makes. And because the ads are automatically removed, I'm certain to get each item twice, with a delay of a couple of days.

Checking some more, it appears that this behavior is caused by missing guids in the feed. And it seems that NetNewsWire does not attempt to figure out if things are duplicate items if there's no guid.
AFAIK the author of the feed wants them to be there, but they're getting stripped out somewhere.

| Without guids, there's no reliable way to detect updated vs. new items. I highly recommend guids -- in fact, I've been recommending them for years. In my opinion it's the single biggest technical issue in the world of RSS.
