It's been tried on other sites (my experience is mainly SO and meta.SO), but it consistently seems to work better to *not* do this.

Ask Ubuntu is a ***question and answer site**,* and we should keep that focus rather than trying to be everything for everyone.  Ask Ubuntu doesn't have to be and *shouldn't be* the only Ubuntu resource people use.  (I've said similar things about SO [before](http://meta.stackoverflow.com/questions/45740/rename-subjective-and-argumentative-close-reason-to-argumentative-inflammat/45743#45743).)  Ubuntu in particular has a [dedicated wiki](https://wiki.ubuntu.com/) for other, non-Q&A types of content.

This shows, probably better than I can, the focus of Stack Exchange:

> This isn't really a place for broad introspection. It's problem specific. You come here because you have a detailed problem or narrow question you want to answer.

Even [our FAQ questions](http://meta.askubuntu.com/questions/tagged/faq) should follow the "[Jeopardy principle](http://askubuntu.com/faq)":

> It's also perfectly fine to ask and answer your own question, as long as you pretend you're on Jeopardy: phrase it in the form of a question.

In cases such as FAQs, it makes sense to have one "primary" answer which is updated by everyone — and this is the point of CW — but they still ask a question in the question and provide answers with the answers. (It may be useful to look through the history of [SO's community FAQ](http://meta.stackoverflow.com/q/7931), which started on SO itself when SO was just a single site.  However, much of the earliest history is only available to those with 10k rep as the questions have been migrated and deleted.)

Specifically about the on the question you mention: posting more answers which people incorporate into the question body simply won't work.  This requires careful coordination from all posters to delete their answer once moved, but since that won't happen, it also requires a moderator spending *lots* of time maintaining just those questions.  Neither is a good idea, and in practice will lead to detritus and a failed question.

There is a rep requirement to edit community wiki posts, but it's rather low at 100.  This level reflects that you have some basic experience with Stack Exchange sites, such as the mechanics of markdown, asking, answering, commenting, etc.  Remember you can start at 101 rep with enough experience on another SE site.  If people are trying to reach 100 rep and failing, we have a much bigger and completely different problem.

**I would vote to close as "not a real question":**

> It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, **overly broad,** or rhetorical and **cannot be reasonably answered in its current form**.
