Rankings of Blogs by Law Professors

OpinioJuris has listed a ranking of blogs by Law Professors on the basis of "average visit length." Paul Caron at TaxProf has also done a ranking based on the overall number of site visitors. One of my professors, Michael Scaperlanda, has a blog called Mirror of Justice, which is ranked sixth in the length of visits, but ranked 26th in the number of visits and page views.
