Thanks, I actually read!

"The Go devs have since stated that they were surprised to see that a lot of Go converts were from dynamic languages like Python and not C or C++. Go still makes sense for a lot of apps ... somewhere, however, that has been extrapolated to the idea that Go is a good language for writing web apps."

I think this is the crux of the question. And heck, it's very easy to spin up a web server in Go, and so many intro examples focus on that.
