I just added this feature to the beta branch of Simple Facebook Connect. It pulls comments back from auto-published stories and integrates them into the normal comments stream.
Features:
- Integrated with Auto-Publish. When you post, and it’s auto-published to your Page or Profile, SFC notices and saves the resulting story IDs for later polling.
- Fast. Every 6 hours (maximum), comments are pulled from Facebook and cached locally. Comments are only pulled when needed, if nobody’s looking at old posts, then FB comments are not pulled for it.
- The comments are added to the normal comments listing.
- FB Avatars are displayed for them.
- A “facebook” class is added to these comments for separate styling.
- Works with user comments or “Page” comments.
TODO List for this:
- Add a link back to the FB comment so people can reply there instead
