If you come from a Scala background, you will find Go pretty 'Meh' feature-wise (No offense). It's a great language, but still it has a long way to go. With that said, I personally want Go to succeed as I love it's syntax (compared to Scala's slightly hair-pulling syntax).
Also, the lack of robust battle-tested web-frameworks is right now a show stopper for me.
