I've made at least a dozen LOB Rails apps for internal use at companies. I also worked at a bespoke consultancy that made Rails sites for startups, and I've seen dozens of Rails apps "in production," out on the open internet, and making money for their owners. I think there may be some conflation here between "production" and "Twitter- or Facebook-scale production." And I wouldn't trust ANY framework to applications at that scale.
Even for internal use, you have to worry about data integrity a lot of the time.

Ah, so didn't have to handle the maintenance burden afterwards. I did. Rails is awesome if you can just dump the maintenance burden on someone else and move on.
Wha...? Honestly, the presumption on this board sometimes. I was one of the 2 people who maintained the apps on AWS. There were no issues. I guess we've just had VERY different experiences.
