I use Go very heavily for "duct tape" in production, combining processes like machine vision, VNC clients, and video transcoding into a uniform internal API. It has been conceptually a lot easier to work with than my native Python since it offers better (for me) abstractions and a very manageable concurrency model.

Using Go in a professional setting really isn't a technical challenge. The biggest concern is if you have to grow your team, you're either going to have to teach Go (which isn't that hard -- I've seen two different people come from dynamic languages and pick the basics up in a week) or hire people who know Go (often already happily employed).

To further mangle Charles V: "I speak Spanish to God, German to my horse, and Go to connections that might make me wait."
