[1]http://forums.thedailywtf.com/forums/t/27755.aspx -- it was also on HN but I'm too lazy to dig out the thread.
For what it's worth, "Go" as a language is not really implicated in that, it's more like the `go` cmdline suite that was causing trouble. I would also contend that the devs were being foolish to do what they did... Assuming everything was in a git repo, the toolchain makes proper use of submodules, and to my mind this sounds like a case of developers fundamentally misunderstanding git, not Go per se.
But my "railing on Rails" (and, to a lesser extend, Node, Django, etc) will not focus on Go... it's more of a general critique about the lifecycle of large software projects written in dynamic languages.
