I think it's interesting because it's focussed on people who may not be the most famous (except the Gaga one) or you might think as "the most influencial" but when you think about it, they are making changes.
Lula is exceptional, what he is doing for his country is outstanding and is helping his country to become one of the biggest leader in 50 years. He really deserves that spot. Still, he isn't that much in the public eye like Obama is.
Gaga was an obvious choice, love her or hate her, she owned the industry in 2009, she was everywhere.
I wasn't expecting Clinton because Oprah Winfrey was the favourite (she's been named 7 times) but he's done more good than he did when he was President, he's a kind guy.
I love the cover too
