Golang News is written in Go.
I’ve written a few other websites including high traffic sites in Go on a similar stack. Go is quite well suited to this sort of full stack web app I think. Haven’t met any significant hurdles while doing this.
The go blog is also written in go, though that’s quite a small app. I’d be interested in seeing some other examples of this sort of complex app as well.
What sort of app were you thinking of making?
