That's what's awesome about it! Everybody who uses it gets the same impressions of it (EDIT: and those impressions are 95% good). What other language has that going for it?
I think Peaker is right, I think a lot of us who are coming from Clojure/Scala/Haskell/Ocaml/etc don't bother writing blog posts that we're unimpressed.
I've seen a few Haskellers finding similarities and praising Go[1]. Go is just meant to be practical and familiar to most working engineers and all the articles are going to reflect that. Most of the people coming from "advanced languages" are looking for new paradigms to move forward. When it comes to Go, there really isn't much to talk about besides the maturation of the toolchain.
The plenty of Haskellers I know have all expressed disinterest in Go as a poorly designed language.
The linked post seems to be a very superficial take of Go. I wonder if he'd keep his opinion of Go after learning about lack of generics, error product types, nulls, mutability of concurrent messages, and all the other show stopper design mistakes...
It's a library/compatibility problem, and it's (finally) being addressed now (will take years until the change takes place, need deprecation warnings for a loong time).
What? Everyone coming from python/ruby/javascript maybe, but there's also a heck of a lot of us who wanted to like go but find it too primitive and inexpressive. I tried go while I was still a confused haskell noob, and I still had to go back to haskell. I can't imagine how bad go must feel to an experienced haskell dev.
