If they served no function, they would have been worked out of the gene pool by now. A developer can build, but what can sell and actually selling it are another matter entirely. I really gained a lot of respect for sales people at one startup I worked for. How they were able to cold call into a company and find a need and money to pay for addressing it is pretty amazing (to me anyway).
