Are people really having such trouble with the context of this article? The author's name is in the headline (maybe it was modded in later, to be fair), but also there's an "author" link[0] in plain sight. PG's essay's don't have a "who am I" introduction, and if you didn't know who he was then you'd simply click on the obvious "bio" link.
