There is a use case, but internet hype has gotten everyone wanting to use Mongo when there's no real reason to. Postgres scales nearly as well as Mongo while being a lot more flexible. That said, Mongo has some real benefits for non-relational computing (see mapreduce) that could make some of the abstraction headaches and lack of data model flexibility worth it for very large data sets. But I sort of agree; Mongo tends to be overused by startups who are trying to solve a scalability / performance problem before they have one. In the process they often end up running into data model limitations because stuff moves fast early on and you can't foresee what you'll need in a year.
