I could not agree more with you. Even if I created Pygreen I would not use it for big projects. But I know what I'm doing when I create my small web sites and I know for a simple static web site 'start with html and add dynamic bits' is just fine. See it as a bash script, it's not meant to be readable nor reusable. It's quickly created code that serves for one purpose.

I'm the first to say it's quick&dirty. Yet quick&dirty has its advantages in some cases, even for good programmers that know how to make solid and maintainable applications.
