Seeking Alpha Healthcare Contributor Rankings April 20, 2015

Can anyone explain this to me?  The explanation I’ve received from my editors is that the rankings of contributors on Seeking Alpha are made based upon the total number of page views in the last 90 days.  Is that anyway to to arrive at a ranking system that anyone would interpret as based upon some form of quality such as percentage of successful picks; average investment return; number of Pro articles; follower to article ratio, etc; etc; etc?  Clearly not!
