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.
Sorry have you just woken up and missed the last 20 years ?
Almost every single IT company exaggerates claims, says their product is "the best" and "amazing" and suitable for every use case under the sun. Oracle did it. Microsoft did it. Mongo did it. And thousands of companies in the future will do it in the future. It's called Marketing.
And I think you should speak to all these customers (http://www.mongodb.com/who-uses-mongodb) and tell them they don't serve any real world need. I would imagine a few would ask the same question of you.
I think "ORGANIZATIONS CREATING APPLICATIONS NEVER BEFORE POSSIBLE" about sums it up on their "who uses" page... There's nothing in particular that mongo does better than it's competitors.
