While exercising this evening, I listened to a great troika of stories about AIDS in Africa from the CBC’s Dispatches:
From Botswana, a story about a job to die for. We’ll meet Cynthia, Miss H.I.V.
South Africa’s open secret; why Johannesburg is one of the most dangerous cities in the world for women.
And, some soft voices of salvation from another African landscape tainted by disease.
They’re not all gloomy stories of the ravaging disease–they offer a real diversity, and one of them is fairly hopeful. The quality of the contributors’ narration varies, but other than that, it’s the best half-hour of radio I’ve listened to in a while.
You can listen to the MP3 or the RealAudio feed. The program cites a small section of Stephen Lewis’s Massey Lecture, and it sounds fascinating.

Many of CBC’s podcasts are good, but “Dispatches” and “Ideas” are consistently, remarkably excellent. I also love “Quirks and Quarks,” but it’s been a podcast for so long I hardly count it as part of the others in the group.
