I think the statement themartorana is probably contextually inaccurate.
That being said, there are plenty of stories coming out about how companies are evaluating Go and seeing performance increases in mission critical application; as opposed to stories of people ripping out pieces of Go and replacing it with something more optimal for their situation.
Yup, those should have been two separate statements:
1. Node made a bigger initial splash than go
2. A large number of organizations that deal with high-volume, highly-concurrent data sets and API traffic are either in production with Go, or are experimenting with it. (All the companies I mentioned have Go in production)
