Since Facebook made Timeline now public, the my app post using stream publish does not appear in user's Timeline, only in News Feed. Is there's anything we should do about this or anything new on publish stream or feed post regarding the new Timeline feature ?
Your application should have read_stream publish_stream and permissions (I think this is enough). You should send POST request to this URL https://graph.facebook.com/PROFILE_ID/feed
