The Daring Fireball feed (15k subscriber) seems to have issues.
Newsblur reports a 553 error (not an rss feed) but the feed URL looks correct.
Can you have a look?
I am using
https:// daringfireball.net/feeds/main (put a space so it displays vs converting to link etc)
and this works fine
I think it’s just that the switch to new “beta” Newsblur broke JSON feeds. Traditional RSS feeds are XML, and an XML parser will definitely fail on JSON data. There were a few places that added support for JSON feeds starting a few years ago, but adoption is still really low compared to existing RSS deployments.
It stopped working a few days ago, it is more recent than the beta release 
Just pushed a fixed for JSON feeds that use a different author_name structure. This feed should now be working.
Sorry to bump an old thread, but I am seeing what I believe to be the same behavior again. I use the Daring Fireball URL and have not seen any items for at least a week. Please let me know if there is other data I can provide to assist you in troubleshooting.
I also subscribe to the feed, the same URL as you have. I’ve had updates to that feed, some today even, normally its at the rate of 2-3 a day. Have you maybe got any training on the feed? Now and then I accidentally change my view from Feed (bottom left of river of news) to one of the other things and it stopped seeing stories based on the view being not correct for how I expected it, worth checking.

Oh wow, I do not actively ‘train’ via thumbs up/likes and such. But that was probably the hint that I needed. Looking at the training config, everything from ‘author:Gruber’ was disliked, which for this site is probably the reason. I have cleared that and will assume that things will get better.
Many thanks
