If you go to your article and click on "article history" you should see the feedback on the right-hand side. Mine is a general feedback, and if you'd like a more thorough breakdown of my edits, just let me know and i'll get them to you as soon as possible.
As for the ranking, here's a link to help you out. http://bleacherreport.com/writer_rankings
It's basically just a measure of your involvement here at Bleacher Report.
