What kind of "beginner"? If you mean someone who has never programmed before, Go is much simpler to learn than C and makes a lot more sense.

If you mean someone that is a programmer and hasn't used go before, I can tell you I went from "never having seen Go before" to "reasonably proficient" inside of two months. Further, my Go code is easier to read and maintain than anything I've done in other languages. (I came largely from Java, so maybe that's not saying much.)

I think that for beginners of either kind, the documentation and community support are just as important as the language itself. I mean, look at something like JavaScript, which is picked up by "beginners" all the time and is, frankly, obtuse as hell. Go has great docs and a really friendly and helpful community.
