Facebook users average 3.74 degrees of separation

People share to friends and strangers across the Facebook network.

This does bring into question the value of social media on Facebook.  Whilst we may be all closely interlinked through Facebook, the similarities between people beyond their closest friends (location, work. Lifestyle, age, etc) change dramatically.  Mathematics aside, unless you have the global footprint of Coca-Cola, is there value in someone sharing your advertising to irrelevant audiences?  How brands code messaging to create different responses from different audiences should be a consideration.
