At Passover, Jews all over the world sit down for a Seder meal, enacting an ancient ritual. But this year, many of them will be guided through it by a very modern text — a crowd-sourced haggadah. Designer Eileen Levinson launched a website inviting anybody who wants to contribute selections for the Passover service. It now boasts over 2,000 contributions — from children's activities to songs to interpretations of the exodus story through the lens of social justice or interfaith relationships — which people can click through to create a personally meaningful document. Deena Prichep reports on how modern technology is being used to create a varied, living document, and how this contemporary practice is very much in the age-old Passover tradition.
