Disclosing HIV and STDs via an e-card. “The site allows users to choose one of six free e-cards to send to their sexual contacts, either unsigned or with a personal message that avoids awkward face-to-face disclosure.

‘It’s not what you brought to the party, it’s what you left with,’ says one e-card featuring a picture of a bare-chested man. ‘I left with an STD. You might have one, too. Get checked out soon.’

‘You’re too hot to be out of action,’ says another.”
