I am enjoying NNG. Not used it is production (yet) - but just getting my feet wet using it. The documentation can be a hit or miss but if you dig about you can find what you need. For example, one link I found was using functionality that is now deprecated - and finding what you should be using instead took longer than planned. Other than this, I do like it and - in the near future - will prefer to use it over ZeroMQ.
