I think that in some respects, the amount of space available on the server might need to be kept within certain bounds. Also the difficulty in finding questions to answer for helpful users, or users looking to help, can increase with the amount of questions to wade through which are bad questions.
I have personally only been using this site for a few days, I gave an inexperienced answer to a problem, and then asked two bad questions (again down to not thinking things through properly). At one point I couldn't even ask any more questions.
So if these bad questions and bad answers were being assessed as no longer needed on the site, it would actually make me happy, as I would appear to be less of an idiot!
On the other hand, as an educational tool, sometimes users have commonality of difficulties. So maybe splitting the site up into different levels of understanding on some topics may be helpful. Hopefully I've made some good suggestions and points here.
If we decide that moving a question off of the main list (it's still visible from the "questions" list) is not what we want on meta, I would rather that be fixed by disabling that feature, rather than through artificially inflating the vote total.

things? And I notice you have still avoided giving any reasons why you think people shouldn't downvote questions if that was decoupled from question visibility. $\endgroup$
