Instapaper, the popular “read it later” app, has added a new social layer in version 3.0. Now you can follow other Instapaper users to see the articles they “like,” or browse through hand-picked articles instantly from Editor’s Picks. Other nifty features include a “smart rotation lock” to detect accidental rotation, and a new built-in web browser to browse for articles in-app. Update available now. [iTunes; Instapaper]
