Haven't tried it, but from the screenshots, it seems you need to open the url in the browser.
If your goal is so the app allows users a quick view of the stories, having a built in viewer would be nice. Personally I hate switching between apps a lot, and I'm guessing using this would mean - Open story; Switch to Safari to read story; Switch back to Hacky to see next story which if you read more than 1-2 articles would get boring quickly. Just an idea for a future version.

Aside from that, good luck and good job.
