Grace Bonney, DesignSponge

From a humble design blog to media empire, Bonney is essentially the heir to Martha Stewart's throne. Her website DesignSponge, launched nearly a decade ago, covers food, furniture, and decorating. It has garnered a loyal following of crafty women who like DIY projects and love to cook. She recently wrote a book by the same name, launched a scholarship for design students, and made an appearance on, you guessed it, the Martha Stewart Show.
