It's interesting to me because Facebook just made the news recently for saying they'd try to come up with something akin to dislike because the "like" is too positive a sentiment for many situations (death of a relative, bad day at work, whatever). In the wake of that, Twitter didn't say "well the favorite is already neutral of emotions, and is more akin to showing support for the thing, positive or negative". Instead, they said "oooh, we want the problem Facebook is facing".
