This is a borderline ad farm, so I flagged it and would encourage others to do the same. The content is stretched so thin, it hurts. A clear attempt at getting eyeballs on the ads without really bringing anything to the table.
Also, I'd recommend that a moderator investigate UXMovement, the user who posted it.
The headline is a little ambiguous, this article is about how to arrange your website menu bar links (and not about how to optimize placing an order in a restaurant, as I first supposed)
While I don't necessarily disagree with you, do you have any research to back this up?
