You can look on the google groups, called go-nuts, and see how many devs are subscribed.

I wouldn't worry about an active market of Go devs to hire. If a language is any good, it'll attract developers. If you're a programmer, you should try out the language to not only do things you can do in other languages (to see how it fares), but more importantly, "What are the new things I can do with Go that use to be hard, but are now easy?"
