Once again, the "write once lots of small websites" people and the "maintain huge web apps" people, will be talking past each other. We share a base layer in HTML, CSS, JS, but the incentives, requirements, job environments, team sizes, couldn't be more different. I wonder about other languages and ecosystems. What would be a similar situation for e.g. C? Is there such a thing?
