BOSTON GLOBE - Jan 29 - Tawkify, a blind-date matchmaking site, bills itself as “the new old way to date.” It is one of several matchmaking start-ups tailored to millennials who seek companionship, but who have no interest in enduring a string of traditional one-on-one dates to find it. “Social club” is how Grouper is billed. Grouper uses members’ Facebook profiles to set up a date between two people — who each invite two friends along, increasing the odds of clicking with someone. MeetCute sends potential matches to a location but doesn’t reveal them to each other, forcing participants to connect with their MeetCute match or with a total stranger. OkCupid just launched Crazy Blind Date, an app that lets users pick a location and a day, then sit back and get paired up someone to go out with. Such casual or creative meet-ups may offer more “guaranteed fun” than the typical dinner or drinks. Making online meet-ups as relaxed as possible could be the way to keep young people on the Web dating scene, said a Northwestern University psychology professor, Eli Finkel, who studies romantic relationships.
