Spun, a mobile app pulling together news stories relevant to a particular city, has signed several content deals with well-known publishers, including A+E Networks, AskMen, Gothamist, Untapped Cities, The Awl Network, CultureMap, and “dozens” more. Spun doesn’t need to partner; it just needs full stories to appear in the RSS feed, or on mobile-optimized Web pages that Spun can display in the app.
