When I develop against MongoDB in python, ruby, or clojure, I consider it less a database and more a persistence layer for my dicts/hashes/hash-maps, with a handy-dandy query functionality built in. Hell, in clojure I usually develop against a hash-map of hash-maps stored in-memory until the project gets far enough to re-implement the data layer (which I've hopefully abstracted well enough to not be a big deal). Think of Mongo less like a schemaless postgres, and more like a persistent redis. Ease-of-use is its true advantage, and I think anyone who exceeds its capacity should be happy to have the problem.
