Or, it is now that we can see how flimsy the article itself turned out to be. By the way: it appears to have been written by Jessie Stricchiola herself (classy move, that).
I didn't come away with the impression that it was flimsy at all. The rant linked to is written by Danny Sullivan, an eminent SEO expert (the most famous one I'm aware of). I would tend to trust his estimation of a person's notability in the SEO industry.
