New ‘Action Links’ make third-party Facebook apps more interactive

Following in the steps of its “actions,” Facebook on Wednesday introduced a new Timeline tool for third-party applications called action links. These customizable links will appear below an app’s post on your timeline or news feed alongside the links for Like and Comment. You’ll start to see the new links immediately on full web versions of Facebook, but they’re not on mobile.

That means Facebook can not only map who you’re friends with, but it and other applications interacting with the social network can also graph the restaurants, books, movies, news articles and cities you like.
