Cortex contributor here/the guy who wrote that article about using Go. The project is on the young side, so we don't have the "footprint" of older projects yet, but if you want to talk to people deploying models with Cortex I'd recommend checking out our Gitter channel: https://gitter.im/cortexlabs/cortex

All of our core contributors + a good number of users are in there, and we're all happy to chat.
