Elwood: What kind of music do you usually have here?

The tendency of web developers to appropriate well defined terms for their limited little world is a bit unsettling.
A web application involves a lot of very different tasks that are detailed in the article, while other programming fields don't necessarily have such a broad set of tasks.
Or, depending on the field, a vastly greater set of tasks.
There is an element of breadth vs depth in this definition. In some types of software engineering it's crucial to have deep expertise of one or a two languages (oracle, or java) but on web development it's often better to have a much broader view of more things.
This is why 17 yo web full stack web developers are more common than deeply experienced .net developers. The former takes constant curiosity and the ability to stay up to date on what's new in a changing field. The latter takes thousands of hours of experience.
And sometimes even hardware all the way to application level.
I don't understand what you mean, what is 'hardware' here?
