From the Pwnie site

The Pwnie Awards is an annual awards ceremony celebrating the achievements and failures of security researchers and the security community. It is also very, very funny.

Wordpess was nominated for the "Mass 0wnage" category. Note the link to Common Vulnerabilities Exposure data. Wordpress has had like 50 in the last year. Movable type has had four in their entire history. This on the heels of my switch to MovableType is reaffirming.
