[WordPress]’s current spot of being the best in breed within the content management space

Respectfully Jeff, thats not even close to true.

WordPress excels at a number of things, and it's done brilliantly to capture that market (blogging, and small & simple websites), but the idea that because it's had more installs than Joomla and Drupal (which are going after a different market) that it's suddenly the "best in breed within the content management space" is ridiculous bro. Simply, and utterly ridiculous.

WordPress has either no, or severely limited:
1. Document management
2. Workflow management
3. Digital asset management
4. Link management
5. User management
6. ESI Caching / CDN ability.
7. WYSIWYG editing
8. Single Sign-on
9. Multi-side Admin
10. Publishing options
11. Access Management
12. Application
13. Multi-lingual
14. n-to-n content sharing
15. Reporting

And thats ok, because you don't need those for blogging. Heck you don't need them for simple websites, which is what WordPress is aiming at...

I’m guessing they just wanted a quick and easy way to make a functional and beautiful website, which is kind of the whole idea of WordPress. - Matt

Quick, Functional and Beautiful.
Thats what WordPress does well, as long as you want that "functional"-ity to be little and specific. Man, even you blogged that the WordPress shop this year is on Joomla. Sadly, advanced functionality that requires multiple n-to-n nodes simply doesn't fit into how WordPress works. (/wave bbPress)

btw: That amazing website by Amazon to show off the power of WordPress is just 1 logo, no menu, 1 blog post - never updated. Oh and the link on the page doesn't work.

I love WordPress, with all it's good stuff and bad stuff, but as someone who spends a large section of his working life running RFP and/or evaluation processes for CMS I can assure you, that WordPress is so far from "best in breed within the content management space" its unreal. It's simply not at the races with some of the bigger players, unlike Drupal which is. I don't know how many websites you run bro, or how many different CMSs you use, but lets celebrate the things WordPress does well and leave the fanboy tub-thumping to Matt ;)
