I've seen other sites have some success drawing in and retaining users via regular community challenge events, e.g. World Building or Code Review.
Since our participation is waning, should we consider doing something similar?
For those not in the know, a community challenge works like this:
- Users suggest various topics or themes. For example, on Earth Science, suggestions have included antarctic and volcanology.
- Everyone else upvotes topics or themes they like.
- Each week, the highest-voted suggestion becomes the weekly topic challenge. A meta post is written up giving a brief summary of the idea (with the featured tag, hopefully), and at the end of the week, users who asked or answered one or more questions about that topic are recognized.
- Repeat until everyone gets tired of the idea or everyone runs out of suggestions.
Should we have these challenges, how often should we have them, and who should be in charge of them?
