WordPress 2.6 released: "a more powerful CMS"

WP has, historically, aimed to solve different problems than Drupal. And I would hope that WordPress doesn't try to become Drupal if the cost is additional complexity, a slower development cycle, and less time to spend refining the documentation and user experience. I wouldn't say that Drupal is more powerful: it's more general-purpose. That is often a source of power, but it also entails being harder to design and develop, harder to use, and very hard to document -- the ecosystem is huge, and diverse, and all the modules evolve at different speeds. To the extent that WP has a tighter focus, they should treasure that feature, and maintain it wisely.
