Greetings to everyone on this cozy little forum!

I fell in love with CouchCMS, fascinated by its speed and ease of use, especially in comparison to WordPress.
Now I wonder whether Couch can replace WordPress altogether and break its monopoly in CMS market?
Can some of you imagine use cases, in which it would be infeasible, impossible, complicated, inconvenient to use CouchCMS and would be better to switch to Wordpess/Drupal/Joomla instead?
Or maybe there are some features in abovementioned CMS'es, which are not present in CouchCMS and not likely to be implemented at any point of time because if it's design?

UPDATE:
Several days passed and this thread is still empty. I think we can consider it good news

My tip: Concentrate on the things CouchCMS CAN do instead of what it cannot...create it...and show the world the power of Couch so more people who can fall in love with it.
