I recently calculated the number of questions per user for all Stack Exchange sites with more than 10,000 questions. The data was taken from the main Stack Exchange page listing all the sites, and I rounded to the nearest 1/100. (Obviously all data is only accurate as of now and can change in the future).

The results below show that Mi Yodeya has far and away the highest number of questions per user. While 4/5 of the sites do not even have one question per user, Mi Yodeya has an astounding 2.6 questions per users! The average for all other sites is .75 questions per user.

Does this tell us anything enlightening about Mi Yodeya?

Why is it that we have so many more questions per user than every other site?

Is this good, bad, or irrelevant?

Is there anything we could or should be doing to change this?

    I was thinking of this in a different context. I think Judaism is very special in that we lean through Q&A. If you think of it, this is not how you learn about other disciplines. I don't think there are dozens of books of Q&A on history, science or arts. I'd say this is one of the key causes of what you detected. – mbloch Sep 12 at 17:42

    It could mean we have high user retention. Maybe that we have a few outliers with lots of questions. It's hard to conclude much from one single statistic. – Double AA Sep 13 at 14:48
  • It might be interesting to display these results with the number of users of each group. – Avrohom Yitzchok Oct 21 at 19:42
  • @AvrohomYitzchok I don't think I saved that data. – Alex Oct 21 at 19:54
