“The Bivings Group” has a good run down of some of the reasons and strengths/weaknesses for choosing WP or Drupal to build a site on.
We’ve been looking a WordPress a bit more these days especially with Stephane coming on board at Plank next month (Wp Ninja).
“Both are fantastic open source blogging platforms/content management systems with robust user communities. Both systems have their strengths and weaknesses. They are great alternatives to closed, paid platforms and much more cost effective than custom builds. As a web development shop, using Drupal and/or WordPress allows us to focus our energies on design and strategy as opposed to reinventing the content management wheel.”
