People talk about South Africa as one of the 21st century's up-and-coming global powers, but it's still home to five million people infected with HIV. The public health care system is completely overwhelmed and misinformation is rife (one billboard campaign from South Africa encourages people who've had unprotected sex to just take a shower).Pop!Tech has cultivated one helpful effort called Project Masiluleke.The first component of the "Project M" idea is to append little snippets of health information (like an AIDS info hotline number or a reminder about a clinic appointment) to short text messages that South Africans are already sending and recieving. In a test, these little text "footers" tripled the number of calls into an AIDS hotline.
