Technology and tradition don't always mix -- witness several ultra-Orthodox communities' resistance to cell phones and internet use --but matchmaking turns out to be an ideal candidate for modernization. "Traditionally matchmakers only had 100 people they might set you up with," says Marc Goldmann, co-founder of SawYouAtSinai. But online dating expands that pool to tens of thousands of people and erases the "blind" element of the classic set-up. As Goldmann puts it, greater efficiency means better matches.
The site has been so successful that Goldmann and co-founder Alan Cutter have replicated the service for non-Orthodox Jews and hope to do the same for Mormons as well as South Asian expats. The duo has even been approached by alumni associations looking for novel ways to foster romance after graduation (and to spur fundraising while they're at it).
