> Go in my opinion is the best proof that our industry is fashion driven.
Go itself isn't flashy or trendy or fashionable. It doesn't introduce exciting new concepts. It's as notable for what it doesn't include as what it does include. It is, in my experience, an extremely practical and pragmatic language. Saying it's proof of a fashion-driven industry is like saying the Honda Accord is proof that the automobile industry is fashion driven.
I believe some of the initial interest in Go was due to its newness and its affiliation with Google. But traffic-baiting bloggers have moved on to the next thing, as have programmers who are more focused on the process of programming (i.e., "I want the act of programming to be fun") than the results. I think it's settling into a comfortable role as a practical choice for teams who want to get work done.
