The Go programming language

So I played a little bit with http://golang.org and I must say I like it. So please tell me why it is shit because I know /prog/ knows better.

I don't think it brings much new to the table.
It has light-weight threads and channels, which isn't really my preferred concurrency paradigm. And it compiles faster than C++, which is almost a tautology.
I think it might be geared toward servers/services, but then why not use Erlang?
