You don't really need a web framework with go. net/http is just fine for most use cases.

I haven't had a pressing need for using it, and I'm considering it as something I want to learn on the side for now.

As for frameworks, it seems the http package comes builtin with a server and a url router. Also, Google's AppEngine supports Go.

web.go is still not compliant with the recently released Go1. I'd recommend anyone interested in Go but not in a hurry to wait a month or two until the Go1 dust settles.
