This is a great technique, because despite the mood in the echochamber here sometimes (I also have absolutely zero interest in using them), many many users legitimately do want to like things or share things or interact with social widget whatevers at some point on some sites. Using libraries like this makes that interaction absolutely explicit, with minimal loss of ease of use, which means that nothing is shared until that explicit signal that the user wants to share.
