One of the comments in the original article said that developers use MongoDB because they're too lazy to use RDBMS. I don't see anything wrong with that - laziness is a virtue among developers! Seriously though, we are using MongoDB with great success at StartHQ (https://starthq.com https://starthq.com) having done a lot of work with relational databases before. It's a great fit for startups where the schema is constantly evolving & the amount of data stored can be quite small. Also, by talking to the DB directly, without an ORM, we can keep things really simple. I dread to think of what the same code would look like if we were to use a relational database, either with or without an ORM.
