The overall document-oriented approach of CouchDB and the free-form way of saving data are probably the things that appeal to most of us when we first read about this new database.
Most of the people that were introduced to CouchDB so far quickly made the decision to use it in production despite the early beta’ish state of the project. We all hate normalization, we all want a faster and responsive database, and some of us want multiple nodes and inter-node replication. CouchDB manages to sell all these quite well. And of course, there are plenty of other reasons.
