The problem is not that MongoDB is marketed as a hammer, the problem is that the use case most users have is a screw. I think it is a perception problem among developers who have run into problems scaling apps based on relational databases (read: the screwdriver) that they can just drop in MongoDB and scale away. The problem is that MongoDB isn't a better screwdriver, it is a hammer. If you can rework your app to take advantage of a different database structure (read: nails), then MongoDB could be the right tool to use.
