Remember that a successful software platform (Open source or not) has to come with a grown up ecosystem. While WP 3 is definitely a better CMS, the community around it seems destined to stay on the blogger side of things where in the Drupal community we aspire to build complex things and keep pushing the bar upwards. Design firms love WP, but design firms dont launch serious sites, they design them.
Also, I second Boris' comments about Acquia. It is a bit annoying that everyone in the media says that so matter of factly when even Acquia is saying it is not true. Last time someone from Acquia itself (Bryan House) had to correct you I believe.
Despite that, I do enjoy your columns on OSS
