InstaReader Sync is a service to automatically sync your Starred Items in Google Reader, with your InstaPaper's read-later list. So that when you're skimming the thousands of items flowing in from you favorite sites, you just have to click ☆ on the ones that seem interesting, and they will automatically be available in InstaPaper a few minutes later. It also works with NetNewsWire's Flagged Items.

Tools, toys, features, and applications to get content into and out of Instapaper.
