I see many of the algorithms outlined use time, votes, social influence, but nothing based on pageviews. Is there a reason for that? I mean if a site's PV is spiking, isn't that an indication that it's becoming popular? Or is voting used as a proxy for that?
Going by Pageviews basically gives maximum priority to headlines and encourages linkbait. If a user clicks a link and discovers the page isn't useful (or worse), you don't want to count that as support for the link.
P.S.: please don't submit links with changed titles, ask the question in comments or in a text-submission
