I just read the page you linked to, and can't help to wonder how the post can shell out upwards of $7 million for that. I'm sure the number includes training, integration etc. but it seems to med that a drupal system with some caching, and a few hackers to create newsroom specific modules would be able to do much the same for a fraction of the cost.
You're missing the fact that online publishing is only a small part of what the system has to handle. It has to integrate with the print design tools and publishing systems.
To be fair I imagine there's a pretty complex asset management layer, a ton of legacy code and content migration, and also it sounds like there's a paywall scheme for some content.
Am I missing something obvious?
