Where we use it at LesFurets.com

• Simple UI binding by replacing JSON model by a Dictionary (80% less code)
• Use JSON Dictionary for client/server RPC
• Batch and ETL with an email provider (90% less code)
• Persistence in cassandra (from scratch with 200 lines of code for a whole model)
• Injecting user data in selenium (40% less code)
• Mocking our domain model in thousand of unit tests

... everything in iterative fashion during the past 2 years.
