Noticed a feed wasn’t updating (saw on Twitter that there should be something new).
Checked the site properties and saw that the feed had not been fetched for a couple of days and that it had -1 subscribers.
Did an insta-fetch, which updated the feed. Site now shows as having 0 subscribers.
Newsblur site id is 5998436.
I fixed the youtube subscription code, so when I went to subscribe I got this feed instead: http://www.newsblur.com/site/6317076/miracleofsounds-youtube-videos
What URL did you use to subscribe? I looked now and saw the one I was subscribed to was now 6317076, no idea what happened to 5998436. 6317076 has 2 subscribers.
I tried subscribing again myself using the channel URL and got subscribed to 5999760 with 7 subscribers.
I also see they have different RSS URLs in settings.
6317076 is http://gdata.youtube.com/feeds/base/users/miracleofsound/uploads while 5999760 is https://www.youtube.com/feeds/videos.xml?channel_id=UCSfoxYTlCPFfglckBLrjpsA
The former shouldn’t work any more but I figured your feed fetchers are converting to the new format as I have several sites with that old format that still work.
