A couple of months ago they published a blog post which received coverage on HN talking about how they saved 120k by performing an audit of their infrastructure and killing unused AWS instances. It was obvious from the post that they were in the situation because there were no controls in place. And it didn't sound like they planned to implement any real controls going forward to prevent ending up there again.
