I believe that Twitter fits seasoned internauts (coder, blogger) while Facebook is better for socnet novice (abege, senior, reuni). That’s why Twitter is not a good place for learning. Twitter is for grokking, for contextual communications. If you still need to learn, to link systematically, to easily gather information, Facebook might be for you. Even though, I would suggest you to blog rather than spending your time for Facebook.
