This will get you things that someone else has posted on the active user's timeline with FQL:
SELECT actor_id, created_time, message, attachment FROM stream
WHERE source_id=me() AND actor_id != me()
Question
Is it possible to get the data posted by a person on the timeline of one other person on Facebook?
If it is, how could I do it? Do I need to use FQL queries?
