Perhaps a thread concerning reviews (of all types). I think everyone should be able to agree to “care” about them, I think there is just a discussion to be had about “how much to care” about reviews (of all types).
Edit: Or better yet, perhaps a “How to build feedback” thread where everyone can share tricks and knowledge and practices. The only trouble with this would be the usual spurt of participation followed by the sound of silence other such important threads like this have experienced.
Our community could use a lot more of the skill/resource building types of threads but the ones began often don’t lead to a continuing discussion.
