I don't think you've tried the app he is talking about. The ABC app for iPad is for watching the streaming video of recent shows. It has nothing to do with articles or sharing.

Call me old fashioned, but when I want to share something with a friend, I either tell them about it myself when I see them, or worst case scenario I shoot a quick email that says "Check out the new episode of Castle on abc.com!" The only people I know who wouldn't be able to parse that simple message and then go to the website and watch the show also don't check their email or even have an active account. Not everything has to be an automatic, shareable mini-link that can be pasted into a twitter stream.
