Well written post. Even as a detractor of mongo I'll agree that it works for your use case. But the key is "Our app allows for unlimited user defined forms and fields, some of which may hold grids". That really isn't a very common case. SQL is not great at representing large groups of documents without any common structure.

The vast majority of apps just don't deal with that problem. If MongoDB was really only used by people that its a good fit for (like yourself), it'd really be a niche product. They're marketing it as a general purpose product, which is why they've earned scorn from so many.

Bingo. They should call themselves mongodocs, not mongodb. The way I see it mongodb sees widespread misunderstanding about its use cases and instead of make the use cases more clear, they seem to take an interest in seeing mongodb being used unnecessarily.
