New York ? Calling her new venture “the network built on great intentions,” Oprah Winfrey says her sleeves are rolled up to make the Oprah Winfrey Network “all that I know it can be.”

What will those great intentions look like? Speaking to media buyers Thursday at a presentation by partner Discovery Communications, Winfrey filled in a few of the gaps that have left people wondering just what her round-the-clock network will be since she announced it in January 2008.

After reigning in daytime for a quarter-century, she moves to nights to host a show called “Oprah’s Next Chapter” that will release her from the confines of a studio and talk-show format for conversations and travel around the world.

“I’ll do it anywhere, I’ll do it anytime, with anybody I want,” she summed up saucily.
