OTH there was no Heartbleed bug in the SSL implementation of Go's net/http. So much for hardened implementation. Secondly you can use go behind a http proxy, or even in an FCGI etc environment with minimal change to the code.

It's to be expected that different implementations will have different bugs; that doesn't mean the Go's is better.
That said, it's an advantage of heterogeneity; you get some security by being a small target in a sea of OpenSSL servers.
