"Mother of Learning" feed broken

http://rationalfiction.io/story/mother-of-learning/feed seems to re-add all the entries whenever newsblur checks the site.  Is this a newsblur problem or is the feed deficient?  If the feed is deficient, is it something that newsblur could detect and tell the user about, so I can contact the provider?



Looks like the feed does not validate: https://validator.w3.org/feed/check.cgi?url=http%3A%2F%2Frationalfiction.io%2Fstory%2Fmother-of-lear…

You should contact the publisher and let them know.

Thanks, I passed that along.  Is non-validating feeds something NewsBlur could tell us about when we add a feed?
