Very clever and has already garnered loads of media attention, but I always wonder with ad campaigns like this how much it really adds to the bottom line. Might just be an amusing waste of money.
Reminds me of German satire magazine Titanic, which would enter your name in a raffle for cash if you sent them proof of cancelling a magazine subscription.
This is the perfect time for a whole foods seller to piggyback on this great PR machine and get some publicity for themselves by doing exactly what you suggested.
Imagine, Facebook realizes that people just friend people willy-nilly, so they team up with Burger King to find out who people value less than a tenth of a hamburger (McDonald's quarter-pounders, if memory serves, are $1.25 or so). Pretty slick marketing.
The same people who do the I'm a PC campaign. You know, the one that has a bunch of paid actors all saying "I'm a PC" but doesn't show any machines doing anything.
I think MS missed the mark on that campaign. I wanted them to go for the throat and poke fun at the perceived smugness/hipster attitude of Mac owners. Instead they took the high road ... disappointing.
What's particularly interesting is Apple don't really do the smugness stuff (anymore). If you see the new iPhone ads, it's all iPhone, on screen, doing stuff. MS have enormous potential here, they could just show PCs running games for example, the PC has loads more games than OSX, they win that one hands down. Instead they come off as looking like a poor imitation.
I'm pretty sure there are 10 people on Facebook I only added because we had the benefit of going to the same high school without actually being friends in the first place, so sure why not. Less fluff on my Facebook account, and I get a free burger out of it.
This is the most creative use of a Facebook app I've seen in a long time. Facebook has been making it practically impossible for apps to to incentivize "integration points" (like adding friends). This is essentially incentivizing de-integration!
