You state for web services that spit out JSON that Golang is better. Typically the JSON is a representation of data from a database (relational or otherwise) - how do you envision Golang doing this (spitting out JSON) well? From a cursory look at Golang, I think there is a serious possibility to displace a lot of enterprise Java stuff especially web services that process XML at scale. There is so much baggage and stacks of frameworks to contend with that something much closer to the bare metal, so to speak, would be refreshing to use in that space. But if the DB handling is lacking that could be a turn-off for displacement.
