I don't think you understand how badly 10gen overmarketed Mongo as something that it isn't. I personally believe the people at 10gen deserve legal repercussions (I expect we'll see this in the coming years), even incarceration for the pure lies they spouted that cost companies so much. MongoDB is a trojan horse, a trap, completely incapable of serving any real-world need. If someone thinks MongoDB is working from them, they just don't realize yet how it's subtly broken.
