Honestly, I mostly share(d) your opinion, but am starting to see Go in a different light. The problem is that the community pitches it against C/C++, where Go, with its GC, just doesn't fit well, and Java, whose runtime and libraries is still miles ahead (fast GC, for one).

However, Go seems to be very good at what Python/Ruby/Node.js/Perl are good at. It provides a simple, clean language with more guarantees and better runtime (mainly the cheap goroutines). I see Go taking some of their role for web development, simple tools (Go programs produce a single binary - very easy to distribute).
