You're kinda all over the place trying to defend MongoDB...
So, what is your stake in it? You like it? You have a lot of customers on it and you want to validate your decision?
I'm just curious, because by my tastes, MongoDB is an awful database. It's like the PHP of Databases. It seems like there are a lot of better choices out there especially in the last few years.
Considering MongoDB has only been around for the "last few years", I think it is maturing well. You are certainly free to call it the PHP of Databases, but there are a lot of developers that have learned to use it and are quite happy with it. Seems like most on Hacker News spend more time telling them why they are stupid than actually understanding the tool.
(Also, some guy by the name of Zuckerberg made a TON of money with PHP.)
Also, the tool is still in its toddler years ... and it is constantly compared to tools that have been around years longer (PG/MySQL). Comparing it to other NoSQL databases is just as silly (Riak, Cassandra) because they are completely different, have different constraints and are solving different problems.
There aren't better choices ... there are just different tools that are better for different jobs. It would be like looking at your toolbox and chunking everything but your saw or your hammer. Too many people are looking for the "technology to rule them all", but that doesn't (and shouldn't) exist.
