Hmm. Flud is pretty impressive, so far. Lookout Flipboard.
Solves a lot of issues with property-specific “social readers” and adds followers/following to the Flipboard model. Nice magazine style layouts and UEX, like Flipboard, but you can favorite what you like and then choose, article by article, to share with followers on Flud and/or other social networks like Facebook or Twitter. The property-specific social readers, like Yahoo’s or Washington Post’s, just spam your FB timeline with anything you read. This is really what Digg should have become too.
