"Grouped: How small groups of friends are the key to influence on the social web," the book by Paul Adams @ Facebook (http://www.amazon.com/Grouped-groups-friends-influence-socia...), talks a bit about this.

Anecdotally, I've also seen quite a bit of evidence first hand that suggests the impact of influencers is not clear-cut.
