skimpage works by parsing feed url from a page. Not all pages include feed url unfortunately.
You can try other news website or paste feed URL directly. Then you will get something like this. http://skimpage.com/feeds/524f94b811c69d220b000001

At the very least it should capture the error and give some kind of feedback.
