Guardian-Easy to navigate, yet contains so many stories.
Flipboard--Originally just for iPad, now for iPhone too. Could see how they "shrunk" the content.
Wired-Overall great use of multimedia.
Once Magazine-Places single images large, allows for "soundscapes" or other audio that complements the imagery. Feels like going through a photo book.
News360-website, and apps on all smartphones. Doesn't really work for what we want, but it's a really neat idea for massive amounts of news.
