From NSFW: Give me ad-free conversations, or give me death (please RT):

One of the most popular ideas amongst social marketers is the idea that we will listen to commercial endorsements from our friends because we trust them. Thus, by putting brands into our friends’ mouths, we will somehow trust those brands more by extension. Not for the first time, the marketers have got it backwards. The reason we trust our friends so strongly is precisely because we know that their opinions are not commercially motivated. The moment that ceases to be the case – or we even suspect that it has ceased to be the case – the bond of trust between friends is destroyed. The cocktail party is ruined, society crumbles, the apes take over the world. [Emphasis added.]
