No. He starts off by conceding the point, basically. The title is "Code: It's Trivial." So assume that you can write all of the code for Stack Overflow in a weekend. He lists 13 things that his team spends time on that are not writing code (at least not in the sense of adding new features or fixing already reported bugs).

His point is that writing code is a relatively small part of even a software business. An important part, but no more important than many other things that must be done for a business to succeed.

I believe he meant a direct response to the 'in a weekend' claim itself. Which he doesn't respond to, aside from citing Benjamin Pollack.

The rest of his post is more of what we've had in every thread on the subject: Doing It vs Doing It Well
