In someone else's opinion: "If you're paying any attention at all to Go, you're not learning anything. In fact, it's possible you're damaging your brain. It's projects like these that make Google look really bad and unattractive to programming language researchers, especially as compared to Adobe, IBM, Sun, and Microsoft." http://lambda-the-ultimate.org/node/3896
So there's a controversy, which thankfully means I can be impartial and yet tell you to make up your own mind by trying it out :) Which btw you can do in your browser, at http://golang.org/
Also, take a look at this article: http://news.ycombinator.com/item?id=1891725 It sums up Go's last year.
Does anyone have any experience with this in Go?
But what I would recommend is you get your own experience and come to your own conclusions. It is a simple enough language that doesn't take long to learn.
That or you can listen to all the FUD from people that clearly have not used Go and refuse to do it because it somehow doesn't tick enough checkboxes in their pet features checklist.
