In the US, MTV has launched an online project to raise awareness of HIV among the youth public. The site, called Pos or Not, is conceived like a quiz game: visitors are presented with a series of profiles (like in online dating sites) featuring some information about the person in the photo and a key question. Is the girl or the guy HIV positive or negative?
As in real life, it's impossible to guess the answer. Your intuition can't help you, so don't take risks.
The initiative is sponsored by the Kaiser foundation and tries to take advantage of the viral effect of the "game" prompting visitors on every page to pass the link to a friend.
