If a $1 was given for every time she has been quoted, retweeted or forwarded, she could be topping this list. Instead, Yoani lives in Cuba where she has been one of the most active voices denouncing and informing the world on the sufferings of the Cuban people. She currently has more than 285,000 followers on Twitter (you can follow her @yoanisanchez) and her blog Generacion Y is translated into 17 languages by helpful volunteers across the web. The Castro government has restricted its availability on the island but TIME, El Pais and other publications consider her one of the most influential bloggers in the world. She has also received scores of journalism prizes and awards.
In entertainment: Eva Longoria
This 37-year-old Texican is the ultimate shape-shifter: some days she's a fabulous celeb jetting in and out of LAX in Victoria Beckham dresses and Brian Atwood heels (and getting photographed plenty doing it), and others she's the modern-day version of Dolores Huerta. Whether she's co-chairing President Obama's re-election campaign, speaking at the DNC, producing a documentary on child migrant workers, or raising funds for parents and children living with cancer, Eva has become a master of using her celebrity to change the world.
And then there is her business savvy: her empire includes fragrances, books, and restaurants (she even has plans to open a steakhouse for ladies in Vegas!)
Catch her hosting the ALMA Awards on NBC later this month with her pal George Lopez. The show celebrates the achievements of Latinos in entertainment, something she knows a little something about, not only as highly successful TV actress, but also through her work behind-the-scenes with her production company, unbeliEVAble Entertainment, creating culturally relevant shows.
Add some endorsements into the mix (L'Oreal, Lays, Pepsi Next, to name a few), and it's only a matter of time before she takes over the world.
