Should this question have been closed?
This site does not operate any policy of "Allow X by making it Community Wiki" that you might find on other sites on the network. We find Community Wiki is best used as a tool for collaboration of easy editing, not as an enabler for classes of questions that would otherwise be off-topic. If a question is acceptable, it's generally appreciated that it should be acceptable without needing Community Wiki. That way, it is clearer that the material we accept is considered valuable and authoritative, as we reward it all. Also, Community Wiki only ever solved half the problems of list questions, anyway, but I digress as that's a tangent.
These are list questions that play out very similarly to shopping advice. Our normal response to such questions is "Teach people how to fish", to start over-using that proverb. We transform "What video game recording software is there?" into "How can I record videos of my gameplay?". Many of our fully prohibited and closed shopping advice questions occur because they cannot be suitably transformed into a practical problem that has conclusive answers. Thus if they are unable to find a comfortable fix, they remain in their itemized list state and are off-topic here.
I don't think that is necessarily true; one question of that type may be tolerated but I'd say that's a far cry from being "valid". Per
It’s tempting to start with easy, superficial questions: surveys, polls, and rudimentary questions like “what are some good books on this topic” or “what are the best blogs on this topic.” Those are not good questions for the private beta – they don’t reflect the actual content that we want this site to contain, and are not representative of it.
(this is a mandatory clickthrough page for every user's first question in a private beta as of a few months ago..)
