Mongo is also brilliant for internal tools that need to change rapidly but you absolutely know will never require significant scale. I've been badly burnt trying to use mongo on a large dataset but it's genuinely great for getting things done quickly. I also used it to write a service that had to go from nothing to working in a couple of days. I then spent the next two days swapping it back out again. It was surprisingly painless to go from an object store to a relational model
