I'm an elected moderator on Mi Yodeya, The Workplace, and Worldbuilding, and a pro-tempore mod on Writers. Professionally, I'm a technical writer who works with (and often helps design) programming interfaces. I'd love to see more tech-writing questions on Writers.SE.
I joined Stack Exchange so I could commit to the proposal for Mi Yodeya. I ask lots of questions to learn from the many knowledgeable Yodeyans. My answers tend to be mostly to practical "Jewish life" questions.
Please check out Mi Yodeya's publications with Q&A drawn from our site -- a haggadah supplement for Pesach, a Purim collection, eight nights of Q&A for Chanukah, and our newest, a collection for the high holy days.
Stack Exchange has many great sites. However, I recommend strongly that Jews avoid Biblical Hermeneutics or, at the very least, consult your rabbi first.
