These questions and their answers (follow the links above) all come from Mi Yodeya, the online Jewish Q&A community on the Stack Exchange network. This community of hundreds of active participants (and hundreds more of occasional ones) has asked and answered close to 18,000 Jewish questions over the last years. One person thinks of an interesting question and puts it out there. A couple of others think of sources that help address that question and share those. Still others vote the best stuff up and the worst down. The result is a highly intriguing mix with something for everyone.
