Not content to merely soak up the publicity lauded on her from SocialiteRank.com, Tinsley Mortimer is bringing on the heavies to find out who's behind the anonymously-penned privileged set chronicle. She's reportedly hired a private investigator to unmask the purveyors, even though the Tinz is regularly placed atop its weekly rankings of social climbers. Sure, taking the top spot brings with it plenty of criticism, but it's also help boost her into a classy version of Paris Hilton's limelight. With all the speculation about who's behind the site – Derek Blasberg, Lyle Maltz, Bonnie Morrison, and "anyone who has anything to do with R. Couri Hay" – it's also worth noting how much attention the blog has received. And certainly such an accomplishment takes a well-tenured publicist. Or a Brooke Astor hopeful in training.
