On: "Pen Science" is to Writing as CS is to Web 2.0

"The point of the analogy is that the implementation -- essentially what CS is all about..."

Computer Science is not about how to build a computer.

Computer Science is about what you can do with a computer. Google's pagerank is computer science. Recommendation systems, like Amazon and Netflix use, are computer science. Computer science is about discovering new ways to design bridges -- not about building them.

Computer Science is not about how to build a computer.

Implementation here refers to software as well.

Computer Science is about what you can do with a computer.

Not really. The vast majority of CS research papers are not about new uses of a computer.
