There's nothing inherently wrong with your "I need a comprehensive list" question; It's just that we specifically forgo asking these types of questions because they are not a good fit for this type of Q&A site.
Stack Exchange is well-suited to asking very specific questions that represent real problems you encounter in your day-to-day work. A big part of that process is asking very long-tailed questions; the kind where folks with specific expertise in the subject can propose the best possible answer, which is then voted on so the best possible answers rise to the top.
Asking everyone to contribute to a large bucket of answers means that it stops being a question of specific expertise and becomes a "poll" of the community. For right or for wrong, answer start accumulating and people start voting on what they recognize as familiar, rather than vetting the relative merits of each answer. Often there are too many entries to even know what anyone is contributing anymore. It doesn't even matter; There's usually no expectation that any one answer will be better than any other.
What I am saying is that the Big List™ breaks down the whole premise of why we created these sites in the first place — to vet and deem the information contained in the post as useful. Marking a question as "community wiki" does not take away from the inherent randomness of the discussion that becomes the thread.
This isn't a personal attack on the value of asking these questions. There just might be — and that's a big "might" — a value in just having the list, but creating these "polls" is simply not what we do here.
