Everyone is a consumer marketer, just like everyone is a product designer, because everyone receives marketing and uses products.
Of course this is completely wrong.
For example, the word the.
We say the. We say the iPhone.
We say the Nexus.
What does Marketing say?
They say something different. Something carefully chosen. No the. The is demeaning.
So the difference between what enters your mind and you begin saying, and the marketing itself, that is the difference between what the expert designs and what everyman experiences.
