Tatiana Platt is a socialite, former AOL executive, and the wife of architect (and man-about-town) Campion Platt. These days, Tatiana is working on a new project, the website called Famegame.com. It's amusing stuff: If, say, you attend eight events a week and you're wondering if you're quite as ubiquitous as Daniel Benedict or Tinsley Mortimer, it's a godsend, spitting out a popularity rating based on how long you lingered on the red carpet and how many photos of you were then uploaded to a site like patrickmcmullan.com. And there are dozens of society-obsessed attention addicts who check their scores daily. Unfortunately, while it's nice that Tatiana took some time to describe the site in detail in this week's Observer, she seems to have a small problem getting the details of her own life straight. After the jump, the tall tales of Tatiana Simone Gau Platt.
