I think it's a mistake to generalize from those RWW commenters to "normal users." Of the millions of people who logged on to Facebook yesterday, many thousands probably got there via Google, and just a few hundred ended up commenting on various highly-ranked posts (though there were probably many more who clicked the posts but didn't comment). The commenters are not representative of normal Facebook users; they are a very aggressively filtered 99.99th percentile of the users who have the most trouble navigating the web.
