In Battle Against H.I.V., Using Facebook and Twitter – NYTimes.com
The online banter was too steamy to ignore.
Gregory Johnson, a soft-spoken young man using the screen name “Adonis,” talked up sex to several hundred of his closest Facebook friends this spring. Once he had their attention, he sent a racy snapshot of two square wrappers tucked into his underwear along with a plea: Why not use a condom?
It was only a matter of time before the social media that keeps friends and family connected and amused was pressed into public service. Just as antismoking ads have come to saturate the airwaves, a flurry of personalized messages promoting H.I.V. testing and protected sex have popped up on thousands of smartphones, iPads and laptops in recent months.
