Please have a look at this question:
As it is just now, it's a question that's looking to start a discussion. It specifically is asking for multiple answers, and doesn't really meet the criteria for a useful community wiki question (which, admittedly are still vague).
I've closed it for now, because I think it'll attract chatty answers, and I think the question will be a lot more difficult to improve once it does that. However, I think there's the core of a good question in here.
- How can this be edited into a good subjective question? (Anyone who hasn't read it may find Good Subjective, Bad Subjective on the SE blog extremely useful.)
- The best uses of CW I've seen are questions where the answers are useful on their own, and a good reference. If the community wants to re-open this as a good community wiki question, how can it be modified to be a good, evolving reference?
