What I didn't realize was that there's also a mobile application to allow you to add things to your Read It Later list on the go. The free app has iPhone, Android, BlackBerry, and Pre applications that give you easy access to your saved content. In the latest, just-released update, Read It Later organizes saved headlines into a "Digest," grouping by category. This way, you're not presented with a long list of unorganized, unread items. While the add-on and applications do the sorting automatically, you are able to edit your preferences and add new categories and share your digest with others.
