I can't decide if this is a successful brand stunt or a completely unnecessary monkeying with a brand's Facebook page.
Burger King Norway opted in for a ballsy move to find out. In order to see which ones among their FB fans really, trully love Burger King, BK gave them a loyalty test. Or, rather, they offered them a Big Mac via BK's FB page. Those who decided to go for it, got a goodbye letter and a voucher for a Big Mac.
30K fans decided they'd rather have a one-time Big Mac than the lifetime of BK FB updates.
8K of those who stayed are, however, ready to die for BK.
(and McDonald's marked an unexplained surge in traffic during the stunt)
