The idea of topic challenges was originally suggested by Jon Ericson and has been used by many sites since. I also mentioned this in a recent post asking for ways to promote Lifehacks.SE.
How does it work?
Ask for ideas - a post is made asking the community to suggest ideas for the next weekly topic challenge (home, cleaning, food, etc.). These ideas can be tags that are popular now, or tags you think deserve more attention
Choose an idea and initiate the challenge - the highest voted suggestion will become the weekly topic challenge and a meta post will be made explaining the tag and telling users that it is the featured tag for the week
Tally the results - users who asked or answered at least one question with the tag will be recognized
Repeat until we run out of topics
Should we have topic challenges? They can be weekly or biweekly. Use this question to post any of your own ideas about improving this idea.
Note: participation is encouraged, but not required
We will now have biweekly topic challenges. They will start every other Friday. The first one will be Friday, April 24, 2015. Please suggest topics here.
