New Facebook ‘want’ button – reports

According to several technology blogs, developers have discovered that a Want button has been added to the Facebook Javascript SDK as an XFBML tag – <fb:wants>.

As yet, the button is not publicly listed among the other social plugins on Facebook’s developer site. Developer Tom Waddington from Cut Out + Keep says the button will only work on Open Graph objects marked as “products”.

Currently, with Open Graph, developers have been able to create their own ‘want’ actions, but users have to authorise a third-party app in order for them to generate stories on Timeline and News Feed. If the Want button plugin works like the Like button, users will not have to go through the step of authorising an app.
