@refugee - My experiences have been quite the opposite. Mongo allows me to focus on the domain. AR forces me to think about fitting the relational model into my problem, which causes a huge impedance mismatch, and causes lots of extra work and performance issues.

Of course it depends on the problem, but working with hashes and arrays is simpler than the relational model, no?

I do concede the vast swaths of docs for AR, however AR is pretty complicated and issues arise that aren't well documented.
