There were a big stack of bugs here, activity syndication had not been tested on v10.
I've fixed them.
I also had to upgrade Facebook SDK.
I've also made it easier to debug.
It won't work on your site yet due to: "The user hasn't authorized the application to perform this action". You need to jump through many hoops with Facebook for this nowadays, including recording a screencast of the functionality as it is supposed to work.
The error message can be seen in the facebook-error header that we're now returning if there's an issue. You can see that in the browser's network request logging under the activities_handler.php call (assuming you're testing via direct activity posting).
