News: Weave, Magnify, WP Central, Bing News

Kind of hard to recommend apps since it's usually up to personal preference. For reading news I do recommend Weave and Magnify, they're the closest things I've found to Flipboard which isn't available for WP users. I have Blue Skies and Bing Weather but lately I've just stuck to Bing Weather so that Cortana and the app agree.
If you haven't already downloaded it, Nokia Storyteller is a cool way to view photos. I like how it makes a 30 second vid with your photos and how it arranges photos by location.
