Although I have used Go in the past and do like it - thought I would just point out that nearly every positive about Go you mentioned had 'Good enough' prefix it. Are you actually finding Go good or only enough for your current needs?
As a question: do you see parts of your startup expanding past the area of Go? Would a mixture of other languages help?
