Thanks, Erik!  This is very helpful.  What do you mean by 'back testing'?  

Also, even without boost links, there seems to be a bias towards popular (long pages).  it seems that a focus on # of words in common rather than % is one of the things leading to long articles seeing so much more traction - would this be an easy thing to test as well?
