Interestingly, the owner of the dog with more than five million Facebook fans is Irene Ahn, and she happens to work at Facebook, sort of leading the social network’s finance department. AllThingsD, who first broke the story, said that Ahn used to work for Yahoo and PayPal prior to joining Mark Zuckerberg’s company in December 2008. Apparently Boo’s owner has kept her identity secret to most of the world. When Boo guested on Good Morning America last year, Irene Ahn reportedly stayed off-camera. Even when Boo’s book was published last year, Ahn decided to write it under the pseudonym J.H. Lee. Interesting isn’t it?
