The tributes to poet/American treasure Maya Angelou continued to pour in on Wednesday, just hours after the 86-year-old "I Know Why the Caged Bird Sings" author's body was found in her North Carolina home.

Angelou, the author of 36 books and a high school dropout who earned more than 30 honorary degrees, was one of just five poets to speak at a presidential inauguration. Her poem at Bill Clinton's 1993 inauguration, "On the Pulse of Morning," encapsulated her gift for writing that captured the struggle and triumph of the human spirit. "I am the Tree planted by the River/Which will not be moved," she wrote. "I, the Rock, I the River, I the Tree/I am yours--your Passages have been paid/Lift up your faces, you have a piercing need/For this bright morning dawning for you."

For those, and many other inspirational words and deeds, she was honored by everyone from Snoop Dogg to Mariah Carey, Justin Timberlake, Mary J. Blige and fellow author J.K. Rowling. Rihanna was so moved, in fact, that she changed her Twitter icon to a photo of Angelou.

Carey said she was "so honored and humbled to have been able to meet and speak with the legendary Dr. Maya Angelou," thanking Oprah Winfrey for making the intro to "one of the world's most invaluable treasures. Ms. Angelou's spirit was beautiful..majestic..powerful and pure. Her words will be remembered and they will live on and continue to uplift and heal millions of souls. Rest with the angels."

All great artists draw from the same resource: the human heart, which tells us that we are all more alike than we are unalike.- Maya Angelou
