Is there anything Oprah can't do? Besides hosting possibly the most popular talk show in television history, her company publishes O magazine, and she also co-founded the Oxygen Media television channel. Winfrey even plans to open an academy for girls in South Africa. So if the "Domestic Diva" Martha Stewart was able to take her company public, why not Oprah?

"There's been speculation that she'll do it, but when you're making so much money, why deal with the headache? With cash flow like that, why share it?"
