Everyone can see how many favorites a particular question has. And everyone can go to a specific user's profile to see what questions he or she favorited. But I see no way to find out who favorited any specific question - my own questions in particular are the ones that pique my curiosity. (An interest in seeing like-minded people and all that jazz.) Unless there's an angle I'm not trying, googling turns up zilch. Is there a built-in feature to find favoriters, and if not, is the absence of such deliberate (why)?
As pointed out in the comments, this query will tell you want to know, but the data is typically a month or two behind.
There is no way to retrieve the same information on the site itself and that's currently by design.
