Facebook may be experimenting with new locations for Open Graph actions such as “want to watch,” which it debuted last March for posts from applications, and which were added to posts and lists from friends’ Timelines later that month.
Facebook is expanding its options on mobile with regard to letting users post about media they want to experience — but the site recently told AllFacebook that a recent discovery is a bug. Previously, a user could click on a book that a friend posted about through a sponsored story and say that they’ve read or want to read. Sister site Inside Facebook discovered that now, iOS users (we haven’t seen this for Android yet) can tap sponsored stories about a show or movie to indicate that they have watched or want to watch. Facebook said that this is a bug and that advertisers would not be charged for clicks.
