I find this to be a big advantage for using Go over something like Python or Java. You still need any dynamically linked DLLs, but all the Go code itself and the runtime is statically compiled and linked into the executable produced by gc.
As for the concerns about it not being used in production, there's Heroku: http://blog.golang.org/2011/04/go-at-heroku.html
All this is completely ignoring the fact that the language itself has a really nice syntax, and some excellent concurrency support. Nothing it does is particularly new, but I think Go is greater than the sum of its parts.

And of course google use it internally.

At Google, Go seems to be competing with Python. http://www.quora.com/Which-is-easier-to-program-in-Python-or...
Looks like for certain problems that don't need to interoperate with the larger system and don't need big library support, Go can sneak in.
