The feed for the Noisey website:
Is showing duplicated items. At any given time, some but not all items are doubled up. Sort by “all stories” + “newest first” to see what I mean.
The actual feed ( http://noisey.vice.com/rss ) isn’t publishing duplicates, but it also isn’t using guids, so I’m guessing something weird is happening that makes NewsBlur think old items are new again.
I noticed this a few times, I’ll mark an item as read, then i’ll see it again later. I set it to show read items and, sure enough, there are two of each.
