Thanks for all the replies. I wasn't actually trying to put mongodb (or nosql in general) down, there sure is a use for these technologies. The amount of money just seems staggering (money in the IT world nowadays seems to be off the charts, re. facebook et. al.), and it probably will be hard to put it all to productive use. But it will of course also help to improve the product so no worries :)

And indeed, I do have a relational database with a column that stores json! The horrors :)

You could help me get familiar with mongodb, any good real world tutorials for it? I have played with it just a little.
