Not true at all. As I covered in the "Go 1.1 released" thread[1], there is no "de-facto" web framework, but there are a handful of good ones: web.go, beego & Revel, to start. Think Flask, Sinatra & Django, respectively, in terms of complexity/kitchen sink.
You are right that there is no "great" ORM in the vein of SQLAlchemy/ActiveRecord, but that's partly because: a) the language is young, and b) the language attracts people that don't like the generalisations/performance issues associated with ORMs.

What's a "traditional web app"? A CRUD app in an MVC style? Sure, you won't be able to turn something "big" around in a short amount of time like you can with Django/Rails, but difficult on the opposite end of the spectrum. You can certainly turn around something performant and scalable, and it's unlikely that you will have to strip components out to keep things fast.
You can, however, bolt together a handful of packages (again, see [1]) and go down the Flask-style route, which seems to be becoming more and more popular these days as people eschew the growing complexity of the bigger frameworks.
