I've been using CouchDB for the past six months for the internal product-CMS for my business. Its got a great feature set for what I am using it for. MVCC architecture, master-master replication and stored views make it a natural fit as a backend for internal tools. The benefits actually grow as you get more desginers/artists etc working together; each on their own DB. It seems like all the problems he has are with scaling. I can't comment on that, but I would whole-heartedly recommend it for internal tooling.
