If you’ve been subscribing to any of my RSS feeds, I owe you an apology.
I had recently noticed that they don’t pass validation and did some work to fix that so that my headlines feed would work with EchoFeed.
Part of that work involved changing the <guid> element to use permalinks for posts instead of UNIX timestamps.
As a result, your feed readers think the updated entries are all new.
As far as I can tell, the only fix is to unsubscribe, re-subscribe, and then mark the feed as read. If you find yourself muttering a certain line from Spaceballs, that’s entirely my fault. I apologize for the inconvenience.
