WordPress is the most popular CMS today. Google Trends indicates that WP's popularity is growing at a faster rate than the competition. We've been getting quite a few inquiries from WP users about CiviCRM integration. One of the main stumbling blocks till recently was WP's license which was GPL v2 only which is incompatible with AGPL v3. On Jan 15, 2011 they changed the licence to GPL v2 or later thus making it similar to Drupal / Joomla and also compatible with AGPL v3 (which is the license that CiviCRM uses). This is definitely great news for us to see the licensing situation resolved. You can read more about this licensing change here:
