A great suggestion from Jon Ericson is to have Weekly Topic Challenges, these would involve 4 steps:
Step 1: Ask for topic ideas.
Step 2: Post a challenge.
Step 3: Profit!!!! Tally the results.
Step 4: Repeat until no more topics are left.

What do people think of this idea? Do we want this on Pets.se?
If so, should we start as a biweekly challenge, like we are working on over on Sustainable Living beta, or will we get enough attention to do 1 per week, like we're doing on Gardening & Landscaping beta?
