Seems to me that neither of these questions could have a "right" answer. Isn't that the criteria for CW?
Any question whose answers are submissions for a list (i.e. polls, your favorite X, list of X), the value of the answers is the accumulation and voting on the list... Those should be community wiki.
They should at least be community wiki, but really they should be closed.
Do any of these topics sound like they fit the bill of Asking Real, Expert Questions? They're not even questions, they're polls. And honestly, I'm okay with the occasional poll, but we're seeing way too many at such an early stage. It seems to be kind of a land grab, with different people all hoping to be the proud owner of an "historic" top-voted poll and all the associated badges.
I'm not even a true "expert" in the professional sense, but I look at these questions and go "ugh, boooo-ring." The team has literally begged us in multiple places not to ask these "favourite X" questions because they're fluff and don't work well with the Q&A style of Stack Exchange.
I request an immediate moratorium on these polls so that they don't swamp the front page; once we have a steady flow of real questions about food and cooking, then we can tolerate the occasional poll. Please help close these poll questions!
There are very few 'right' answers in cookery - because opinion and taste form a large part of the associated body of knowledge.
I think the community wiki should be used for recipe swaps.
