The recently updated free USA TODAY 1.1 for iPhone app has a neat new feature. You can post a news link directly from the app to your Facebook or Twitter account.
You can see the result of posting an item to Twitter in the screenshot above. I have my Facebook account set to automatically read and post my tweets. So, everything I post to Twitter eventually gets posted to my Facebook account too. Now, if USA Today and other news apps would app the ability to save to Delicious, I would be very very happy.
