Let me talk about the history(hehe)
I was webmaster of somesite.com from october 2006 to march 2007.
In January 2007, my new boss wanted to port current home made CMS to a solid platform.
My boss choice was Java, using JBoss(I still smile when remember). I've made research by 3 weeks...
Drupal was the winner, core+community comply at least 80% of full somesite.com functionalities,
the other missing had to be just 2 months of customization and integration of special funcionalities, then the theme and final testing.
