<p>We have somewhat of an on-going problem in that "community wiki" is not perfectly defined (and even so far as it is defined in the stackoverflow world, it's conceivable that it should have a different meaning in our context).</p>

<p>Questions such as</p>

<ul>
<li><a href="https://stats.stackexchange.com/questions/1610/is-there-a-way-to-remember-the-definitions-of-type-i-and-type-ii-errors">Is there a way to remember the definitions of Type I and Type II Errors?</a></li>
<li><a href="https://stats.stackexchange.com/questions/22/bayesian-and-frequentist-reasoning-in-plain-english">Bayesian and frequentist reasoning in plain English</a></li>
</ul>

<p>do not have objective answers.  Yet, they "feel" different to me than questions like</p>

<ul>
<li><a href="https://stats.stackexchange.com/questions/3/what-are-some-valuable-statistical-analysis-open-source-projects">What are some valuable Statistical Analysis open source projects?</a></li>
<li><a href="https://stats.stackexchange.com/questions/726/famous-statistician-quotes">Famous statistical quotations</a></li>
</ul>

<p>So the question is: <strong>how should we define "community wiki" for our site?</strong>  Should "list" questions be community wiki, but otherwise subjective questions that are looking for a general answer be left alone?</p>

<p>One reason that I raise this is that making a question "community wiki" removes some of the incentive to provide great answers, but IMO questions such as the former two above require effort and good answers should be rewarded.</p>
