A few years back we tried a question asking contest on Philosophy and History. The format was somewhat flawed, but I think the basic concept is sound. Having a specific suggestion of a type of question to ask about tends to prompt more response than a general call for more questions. So I'd like to suggest running a "weekly topic challenge". The Judaism site ran one a few years ago and it was fairly effective. So I'd like to try a similar series of challenges on this site.
Here's how it will work:
Suggest topics in the answers below.
Next Friday, the organizer* will pick one of the topics and write up a new meta post introducing the challenge for the following week. The topic will be associated with a specific tag so that we can count how many questions were asked.
Anyone who wants to participate asks about the topic of the week.
At the end of the week, the organizer post an answer to the challenge with a count of how many questions were asked and anything else they feel like highlighting (like favorite questions or notable achievements).
The organizer picks a new topic and starts back on step #2.
People are free to add new topics at any time and when the list of topics is exhausted, the challenge series ends. Sometime later, I can run analysis similar to what I did for the Mi Yodeya challenge series. And that's about it.
Please let me know what you think and suggest some topics for the weeks ahead.
