I actually have seen complaints about Go's performance relative to other compiled languages, like C++, D and Java. I don't think it's coincidental that most of the Go converts come from a dynamic-language background. If you're porting from Ruby, 2-3x slower than Java still seems blazing fast.

For me, Go misses the sweet spot entirely. A year ago I was curious about both Go and Clojure, my interest piqued by the strong concurrency support each has. I picked Clojure and have grown more and more confident in that choice.

Why not Go? In a language with nil pointers (Tony Hoare's "billion-dollar mistake"), no generics, and sub-JVM performance, static typing just doesn't seem worth it. Also, poor interop with other languages means Go can only draw from its own small community for libraries (contrast Clojure which makes using mature, well-tested Java libs trivial).

When Rust is more mature, it may be what I hoped Go would be: the safe language, with lightweight threads, that makes me never have to write C or C++ again.

Go didn't stick for me either.

Go is interesting and I really enjoyed channels, but no generic programming really disappointed me. I guess supporting the generic paradigm is pretty tricky (C++/Java templates/generics aren't dear to my heart), but not being able to implement map/filter/reduce functions...
