To be fair...
A lot of organisations employ these SEO types, just to make sure that the structure of their pages is correct for searching, and sorting out meta data, etc etc. Yes, a gibbon could handle it if everything was done properly, but as with many websites that have a huge number of contributors, it isn't.
What strikes me as odd is that the first site mentioned in the article is Digg, yet it was never targeted. The Waxy article even goes as far as to say "In particular, I'm stunned that he didn't go after Digg".
Never mind, eh?
