I'm with you - I don't quite get this considering the Facebook stance on "fake" users. Was a losing battle to fight? Will they now allow parody accounts a la Twitter?
I'm guessing they were building this for pages which desperately need it and decided they'd roll it out to select profiles too while they were at it.
It only really makes sense on profiles either as a vanity metric or as a way to not have to police impersonators.
