Web Development or Computer Science

I love to look at the logs to see how people find this blog. Some of the search strings people use amaze me. Sometimes I’m not sure which to wonder more about – how did that string find my blog or what in the world are they really looking for. Recently I saw a search for “is it better to study computer science or web development” that was a bit of a puzzler. I’m not sure those are separate subjects. Can you do good web development without a grounding in computer science? Can you be a knowledgeable computer scientist without some knowledge of web development? Probably not.

I suspect that at the heart of this question was a vocational idea. What career should they go into? Programming (which is what many people think of when they think of computer science) or web development (which many people don’t seem to be aware requires some computer science to do well).

These days most important web pages have database access, active response, and other “programming” that take them a whole level beyond the static web pages of the past. It’s hard to see how one can keep up with the trends towards AJAX, HTML5, Silverlight, Cloud computing and so much more of the direction of the web without a good computer science background. Sure there are self taught people who do great things  but having a good solid base of computer science knowledge would seem to be a big edge for learning the new technologies.

Related to this is that I keep seeing people list HTML as a programming language. That confuses me. I’ve worked with mark up languages for years (anyone else remember Runoff?) and while they are useful tools I see them as data rather than as programming languages. Are they part of computer science? For sure. They take in data, meta data, process descriptions and much more. But HTML is not a programming language. Perhaps this is part of that whole confusion that has people thinking computer science and programming are the same thing? Are people calling HTML a programming language an attempt by people to try to justify calling web development computer science? If so, I think they are missing the point. Web development is a part of computer science.

It may not have the prestige in academic circles that other parts of CS have but it is growing in importance in the “real world” all the time. I think we really want the people developing the next big web app (think Facebook, Twitter and to know a bit about “the rest” of computer science. What do you think? Is HTML programming? Is web development computer science? Or is it rightly kept separate?
