San Francisco - Francesca Salcido went on 300 dates in 24 hours without breaking a sweat.
Her encounters with aspiring beaus happened online at SpeedDate.com, a US start-up built on a belief that it doesn't take more than 90 seconds to find a life partner.
"We may be using webcams and Internet technologies, but you're still trying to find that chemistry," SpeedDate co-founder Dan Abelon told AFP. "And if it isn't there, you just move on to the next person."
The website and its competitors apply the latest Internet technology to speed dating, a phenomenon that started a decade ago with men and women darting from table to table to chat in rapid-fire succession at a time keeper's signal.
"If people decide they don't like someone, they usually know within 30 seconds," said Stephen Stokols, chief executive of SpeedDate rival WooMe.com.
"If you meet someone you like, three minutes isn't long enough. If you don't like them, 30 seconds is too long."
