@Martin, I agree on the number of updates recently!

One thing that will make Wordpress the leading CMS for quite a while is the ease of upgrading and the speed at which they release updates related to security. After mucking with Joomla for the last 4 years, Wordpress is a breath of fresh air.

Regular users running 2.8.x are still worried about the upgrade process. I made a video Wednesday showing people how to upgrade but they still balk.
