Vance Lucas has an opinion on WordPress being named the best Open Source CMS by Packt Publishing recently.

My knee-jerk "how sad is that?" reaction comes not because I don’t think WordPress is worthy, but because of what it implies about the state of other open source CMS projects. The reaction comes from the fact that a blogging platform is kicking your CMS’s ass in its own category.

He points out that WordPress is, first and foremost, a blogging platform and that it has bridged the gap between blogging tool and CMS so well that it's winning in that category too.

The fact that I can go through literally hundreds of open source content management systems and still end up settling on WordPress because I know it’s the only one that won’t totally confuse my client is what’s sad. Usability and ease of use matter.
