I worked on a similar concept to this many years ago with the author Douglas Rushkoff as a proof-of-concept for the ideas expressed in his book "Nothing Sacred," which was about Jewish text as "open source." Haggadot.com has taken the concept much further and created a truly unique and valuable product that is of enormous benefit to the Jewish community and anyone interested in learning about Jewish traditions.

Nice. But a little off timing. Reading the Haggada was yesterday. 😉
