I added a large feed I created consisting of 38 full articles to my Newz tuel. I validated it through Feed Validator and fpr some reason my Newz tuel accepts the feed but doesn't show any of the items.Kurt said it shows up and looks fine in his Newz tuel, so can a few others try it and let me know if it shows up for you with items.
Here's the feed:
