Pocket, in an update to celebrate the one year anniversary of Read It Later's rebrand, has introduced (among other things) Send to Friend, a new feature that allows for quick, easy sharing of content with friends. Users can accept shared content directly from the Pocket app, using the app's new Inbox. Those sharing can also highlight quotes or add their own comments before sharing, sending them along for friends to read.
When you want to totally reinvent yourself, a new look is definitely a good place to start. If you really want to say "hey, this is a new me!" then a name change can convey that message pretty well. I guess Read It Later wasn't happy with where it was in the hard knock life of an app in the Google Play Store, because it recently went under the knife to get a totally new interface, new features, as well as a new name.
