The point is that he (with mr. Morris, I suppose) made this site quickly, cheap and are able to evolve it on the go, almost without downtime with help of very few people. Another point is that this site is the proof of an approach to software development described in the On Lisp book. So, it is not a gratification, it is just a real-world project they have done for themselves to make money. It is not some showcase or a demo, it is real thing. In case of Django, I think, it will require much more man-hours for building and maintaining and more resources (cost) to run. This is an example of Less is More principle in action: less code (the core language concept) and, as a consequence, less everything - time, people, money. Lisp isn't just a language with parenthesis. It is a whole philosophy (a multi-paradigm language). Well, better to read On Lisp.
