Dear CouchDB fellows,

I feel, like most of you, a strong passion for CouchDB. Since I
started to dig into CouchDB more than five years ago, I engaged more
and more in the CouchDB universe. Ever since I am fascinated and
convinced by the concept of Couchapps and have written plenty of them
and developed tools for composing Couchapps. That being said, I also
had to perceive that the concept of Couchapps and Design Documents
often confuses people. Thats why I agree with Jan that CouchDB should
move towards a clearer system, which is more beginner friendly and
more easy to explain, but still provides all the great special
features, which makes CouchDB so compelling to the advanced users.

Let's keep this discussion focused on how to make CouchDB better.
Nobody wants to remove our beloved shows and lists. This is just an
impulse to open CouchDB to more developers.
