Maybe I'm confused then.  Seems to me that CouchBase is a memcached 
front-end, with CouchDB style replication on the backend.  Serves one 
set of purposes, but very different from the initial way CouchDB is 
presented (back to "CouchDB, the Definitive Guide").  But maybe that's 
why you're now doing CouchBase, and not CouchDB or Cloudant.

Why does it have to be one or the other.  To me, it's the combined set 
of features.  (Parenthetically, MVCC w/ replication is not unique to 
CouchDB - kind of goes back to Lotus Notes, which I believe inspired 
CouchDB :-)

REST is not what makes CouchDB unique.

Well... that's YOUR opinion; granted an important one - but you might 
want to get a better sense of what the broader user base thinks.
> I’ve spent most of my time since 2007 advocating CouchDB to thousands of people in
person and even more online. CouchDB’s “AppServer” features are neither straightforward
nor does the term fit nicely. People are confused by the fact that there are three different
“couchapp” tools in various languages, that you need one of them to manage design docs,
just to query CouchDB (I’m sure glad we have mango now, where the steps are “create index,
start querying”, like in every other database). There is confusion of using “couchapp”
to manage views, when CouchApps mean so much more than just managing map/reduce functions.
I can go on for hours how this is confusing for first-time experiences that people have told
me and keep telling me.

What seems confusing is that the tooling is conflated with the AppServer 

To use a perhaps poor analogy - Jetty is a Java App Server.  There are 
lots of Java IDEs that can be used to generate Java Apps. Somehow, 
people don't get confused about what Jetty does, just because there are 
multiple tool sets.

Personally, what I find confusing is why anyone used Python tooling to 
generate JavaScript webapps, to be loaded into an Erlang-based server.  
The logic behind erica, I kind of understand.

>> Rather than retire the term, or relegate it to obsucrity - market it aggressively!
 Perhaps to the the extent of changing the current tag line on from "A
Database for the Web" to "A Database and Integrated App Server for the Web.”

Can you provide a pointer?  I can't seem to find searchable archive of 
marketing@.  Thanks!
