For sure, MongoDB was not production-ready before 2.0 version but I really think 10gen is doing a really great job on it. A lot could (and will be) improved, lets keep going.

MongoDB stills young and received a ton of attention for its promise. And is really unfair trying to compare it with 20+ years technologies.

MongoDB users stills pay the price to be an early adopter and I'm confident we are doing a great deal and learn a lot.
