How many people are opting in thinking "if I lose I can just unfollow straight away"? I slightly want to opt in just to see it unfold, but frankly I don't want to follow three extra people, and I don't want a bunch of people who don't know who I am following me, so I think I'd end up annoyed with the result either way. Nice idea, though.
