I see an article on arstechnica.com that I don’t see in Newsblur.
I see the article in the RSS feed [ http://feeds.arstechnica.com/arstechnica/index/ ] so maybe it is a NewsBlur parsing error or a RSS feed construction error.
I haven’t checked if there are other articles missing. I just happened to see this one called out on another site, but didn’t see it in my feed.
Article URL: https://arstechnica.com/gadgets/2019/07/raspberry-pi-4-uses-incorrect-usb-c-design-wont-work-with-some-chargers/
RSS feed: http://feeds.arstechnica.com/arstechnica/index/
In the feed, it comes right between these two articles:
Google speaks to fuzzy game-ownership question in new Stadia FAQ
The electric Mini is going into production; deliveries start early 2020
Inside Newsblur I see those two articles, but not this one in the middle.
