If I'm reading you correctly you're saying FB/LNKD aren't substitutes for audience research. I'm with you so far, but wondering if these channels can be cheaper / more effective ways to access that audience. In part because it's a platform people are looking at, and in part because these platforms leverage existing 'once-removed' circles of trust.
