No one can read this article yet it is instantly upvoted to the very top of HN. Goes to show how discussion forums like this one just serve to amplify people's existing biases rather than actually educate them on anything new.
Maybe everyone that is upvoting it can read it b/c they subscribe to the news site, and maybe your comment shows your existing bias about your thoughts on other readers of this discussion forum?
In terms of keyword ranking, from what I've observed the only think taking into account things such as keywords with respect to ranking is the readers voting and flagging.
