I second this. While many developers banter with each other about how marketing people are more or less useless, very few seem to understand that in the vast majority of cases creating a technical solution/product is easier than finding enough clients for it to generate steady income.

Furthermore, it's often the case in my experience that developers miss out the whole point of these products: someone wants to make money and the CMS is merely an instrument that they don't care too much about as long as it helps them achieve their business goals.
