Not talking about immutability at all when talking about CouchDB's (potential?) scaling ability is odd. Even if immutability in DBs was no innovation from CouchDB itself, CouchDB will have raised the level of awareness for immutable DBs and probably drive further development in this area. IMO immutability is the very basis of creating scalable applications. So, when talking about CouchDB and scalability you should talk about why the current CouchDB implementation is not scalable in spite of immutability. Disclaimer: I've only read about CouchDB and never actually used it. I'm not convinced of every feature of CouchDB, I don't think, for example, that it is a good approach to dump type-safety in dbs altogether, though, SQL and RDBMS are not the last word in databases and it is valueable to test other, new models of data storage.
