The word is Quality. Many writing sites do not comprehend the word ‘quality’. These sites do not understand that having a quality items on the front page attracts viewers.
One comes onto a site, reads something really interesting, posts it to Facebook or Twitter, or emails it to someone.
Think of it; how many times have you been on Facebook, seen something interesting and clicked on it?
Having quality items attracts views and encourages people to join.
Having a front page made up of whatever was recently published, regardless of quality, does not attract readers.
The sites which put the best work on the front page gets the most views.
