I use it in my ruby app with mongoid gem. My data is not huge, and I only expose it to my users through a read-only API. I absolutely love the flexibility that mongodb/mongoid offers. It almost feels like not worrying about the DB, states, schema, etc. anymore. Please note that mine is an experimental project, and not a commercial one that I run for business.
