There are a wide variety of influencers out there– from the beer afficianado with a moderate but devoted Twitter following, to the mommy blogger with some favorite products, to perhaps the biggest of them all, Beyonce, who can drop an album sans preemptive marketing efforts with a mere Facebook status.

From the hard-to-find influencers, to the ones on the tip of everyone’s tongues, there is a massive amount of tapped and untapped talent out there. Many are willing and able to work with brands in a way that is true and organic to the content they create.
