HERES A PERFECT EXAMPLE OF THIS PROBLEM AND YOUR ANSWER
you said the overall most popular ones get in the scroll.....
well here is my point....
Cheap Women has scrolled 6 times in the last 30 mintues and its current ranking in cateory is #26 opinion and #51 in most popular
Awesome God has scrolled 5 times in same time period , its current ranking is #9 in religious and #65 in popular.
Yet others...whos rankings are higher in category and who also have been ranked as high or even HIGHER in most popular......are not scrolled.....at all
Something is really messed up.
