Instapaper 3.0 for iPhone and iPad is now available in the App Store and the Instapaper website has been updated to include many of the new features as well.
The biggest new features in 3.0 is that stars are now likes and you can browse likes from friends connected through Facebook, Twitter or your email contacts. You can also share to Facebook, Twitter, Tumblr, Pinboard and Evernote. There’s a new built-in web browser in the iOS apps with editors’ picks. See the full list of new 3.0 features in Marco’s post.
