Surprised they don't have SilverStripe listed on there, that's a great up and coming open source CMS that I've used numerous times when clients demand more out of WP. http://silverstripe.org http://silverstripe.org It's lot more flexible than WP but the admin interface is extremely thick in .js (and buggy), thats my #1 complaint. I've grown fond of WP's admin interface and plugin handling. I use WP for my own stuff because I build around its limitations, and can move quickly with it.
