Plugins sind das CMS

In einem etwas älteren Artikel „Textpattern and WordPress take two very different routes to a release“ stellt Andrew Travers völlig korrekt fest:

Like Drupal and others, WordPress and Textpattern rely on plugins to deliver much of what its users consider essential functionality. They aren’t a nice to have, they are a part of the CMS from the end-user’s perspective.

As such, the code quality of a CMS isn’t in reality judged by its fiercely protected core, but by its more widely used plugins.
