This document discusses Plone, an open source Python content management system (CMS) and content integration framework. It summarizes that Plone is not just a web framework, but rather empowers both developers and non-developers to build complex, information-driven websites and applications through features like collections, forms, workflows, theming and more - without needing to be an experienced programmer. Examples of real-world Plone applications are provided. The document encourages choosing a good CMS like Plone over a plain web framework and outlines Plone's roadmap and an upcoming conference.

6. is a
CMS
Content Management System

7. is a
Content Integration Framework

important?

10. Simple requirements / questions
→ a single simple framework will do

11. A complex system that works is invariably
found to have evolved from a simple system
that worked. The inverse proposition also
appears to be true: A complex system
designed from scratch never works and cannot
be made to work. You have to start over,
beginning with a working simple system.

12. Plone is a good
starting point for
complex information /
content driven requirements

13. but you don’t need to be an
experienced developer
to solve problems with
Plone

A good CMS could be a better choice
than a plain web-framework

28. The Zen of Python - PEP20
Beautiful is better than ugly.
Explicit is better than implicit.
Simple is better than complex.
Complex is better than complicated.
Flat is better than nested.
Sparse is better than dense.
Readability counts.
Special cases aren't special enough to break the rules.
Although practicality beats purity.
Errors should never pass silently.
Unless explicitly silenced.
