Think you can tell if I have HIV?

A new, viral web site conceived by U.S. college students challenges stereotypes about who might be infected with HIV.

The site, www.PosorNot.com, presents viewers with photos of people of different ages, colors and genders, challenging them to guess whether the person has tested positive for the virus that causes AIDS.

The site is considered viral because users can share it with everyone in their e-mail address books with a few clicks.

It was inspired by a nationwide competition asking college students to propose a viral, web-based game on the topic.

I think this is a great initiative and I invite you to visit the website.
