Optimal Response Format

[runpaint]

We currently request everything in YAML. Given that HTTParty abstracts the data formats so well, what are the performance implications of requesting YAML versus JSON or XML?

This would mean that we have to change all the stubbed out data in our tests, which would take a while as the values are more than likely to have changed. I don't see it being such a big problem at the moment.
