I have never used MongoDB in production but have thought about it. To me though it is just another architectural decision that you need to base around risk and reward.

MongoDB is awesome at certain things. But it is still not at a tried and true level as say PostgreSQL or MySQL.

I am skeptical of the article but only because it is all too easy to fault new projects. However I would be curious to know 10gen's development practices as compared to say Postgres or SQLite (I have heard awesome things about SQLite's development testing).

We extensively tested this inside Viralheat with a write heavy load of over 30,000 writes per second and basically it failed our test. It is not robust for the analytics world is the conclusion we came to. Though, I hope it gets better one day...it has potential.

Well, I worked in Vodafone (and Nokia) in very large (laaarge) projects, serving ~50 milions users. Years ago, no hope for NoSQL, we used MySQL. We hit at least 10/20 bugs, solved by 'hotpatch' from Sun. So? I think as developers we should get used to bugs and patches. Should I write a post "don't use MySQL?". We also hit several bugs in the generational garbage collector. Stop using Java? I don't feel the drama here.

Sounds painfully familiar...

I was planning adopt MongoDB for my big project and this post puts some doubts. Is this true? Could anyone confirm or deny this?

There's a lot of anonymity going on here. A new HN account, an unknown company and product, and claims with no evidence.

Why are't links to 10gen's Jira provided? Where's the test code that shows the problems they had with the write lock?

This is an extremely shallow analysis.

There have been plenty.

Is this actually true ? Someone from 10gen needs to confirm and accept it ,if they are.

As if they would officially confirm this...

Confirm or refute , doesn't matter but at least a comment giving some strong evidence would surely work !!
