Er, but those people tend to be for "their" language, and suspicious of others, regardless. Avoiding traditional rivalries may give them some breathing room, but Go is not somehow outside of the tribal fanboy ecosystem.
Indeed, the "OMG GO!1!" tone of many HN stories and comments on the language suggest that it's diving in headfirst...
I don't think so: I'm guessing a lot of Go programmers where Ruby/Python guys before. My main language before Go was Python (every time I needed to do some non-trivial bashy stuff I went for Python) and now unless I need some esotheric library only available in Python (or Lisp) I go straigt for Go. And still like Python, no big deal. Won't bash a language I still like!
