For anyone interested or curious... Huffy for Windows Phone 8 has been pulled from the Store. Prior to this I received a takedown notice from Microsoft, who were responding to an unlawful use of copyright material complaint filed by The Huffington Post.
Unless they've changed their T & C's for their RSS feeds, I thought Huffy was well within the guidelines. To be honest, just not worth arguing about it.
If you already have it installed it should continue to work until such time when the HuffPost changes their schema. Or you can install the Official Huffington Post app for Windows Phone, which was released shortly after the complaint was filed.
