Elizabeth Pisani has been doing the junket since her book, the Wisdom of Whores, was released. Reviews, and interviews galore. The book, I suppose, is trying to batter conventional wisdom on what we think we know about AIDS transmission and treatment. I haven't read the book, so I hope this isn't too much of a simplification. The reviews should give more of an idea.
I saw her HARDtalk last week, in an interview that was remarkable in its level of broken taboos. Go to the HARDtalk page, and watch the interview. On the right hand side of the page, click on the third clip on Africa. She talks about the sexual practices of Africans in relation to the transmission of HIV.
