FAST COMPANY - Aug 19 - Online dating startups are using quirky concepts, and emerging technology--from facial recognition to geolocation. Online dating is a $1.5 billion per year industry in the U.S. Match.com generates ~$400M; eHarmony ~$150 million; and Adult Friend Finder earn ~$250M in annual revenue. On most sites, users take the time-honored route of writing up anecdotes about their lives. OK Cupid broke that model by combining traditional "about me" profiles with a personality test a la 20-questions. Dutch startup Soul2Match is using facial recognition software to pair people with similar bone structure. HowAboutWe requires users to suggest unique date ideas to one another. Spoondate asks its members to disclose what they want to eat and where, to match them based on cravings. Luv@FirstTweet tracks its users’ Twitter history to get a sense of their interests and personality.
