Personally, I would prefer not to see a question that's just a list of all of the available types of grid. Yes, "What tools are useful to organize a GM's notes" managed to do fairly well in that context, but it's a really tough fit for the system. And most such questions do poorly.
"What is important when choosing a grid for you game/system/campaign" (pick one) could do fairly well on its own. I don't believe that it would have any need to be CW.
Compare and contrast questions ("what will happen if I replace grid system X with grid system Y?") can also work well, provided they are scoped to a specific situation, or perhaps of the form "when is grid system X preferable to grid system Y?"
Questions about a specific grid can also do well: "What are the advantages of grid system X?"
Finally, you can always go with "I am in situation X, what would a good grid system to use be?"
In general, if a topic MUST be CW to survive, it's a good sign that it will have problems. The current thinking (as I understand it) is that CW is for the rare question that gains a lot of community support, despite breaking the format.
