I sorta feel the same way - but then I think about the 800(?) employees they have and their combined skillset in database administration, internals, research, philosophy and I'm left feeling like there has got to be a very strong technical and business use case that I just don't see. Like I would imagine that if I were locked in a room with their Sr. product people and devs, they could easily convince most people of mongodb. I would pay money to see a debate style db-off between Postgres' core devs, and representatives from Mongodb.
