<p>I don't think Thomas's question should be community wiki, because it is a focused question. There can be more discussion on the other one. The main reason is that it is not a question. Indeed, as the question is formulated we see the author has already his answer and is interesed in getting people's <strong>view</strong>. I think the question about bayesian is borderline, this other one is also borderline:</p>

<p><a href="https://stats.stackexchange.com/questions/130/clojure-versus-r-advantages-and-disadvantages-for-data-analysis">Clojure versus R: advantages and disadvantages for data analysis</a></p>

<p>Finally I guess we should <strong>keep them as non CW</strong> but remember that this is the border :)  (a question can't be less focused)</p>

<p>The reason why a question asking for people's view (and not a question asking for an answer) should be CW is mechanic. </p>

<ul>
<li>It generates a lot of reactions because when you have an answer it si likely that everyone has an answer.  </li>
<li>People are happy to find a place to talk and vote up. </li>
<li>this type of question is encouraged (because you gain a lot of points) and thousands of answer are given. </li>
<li>stat.stackoverflow becomes a forum. </li>
</ul>

<p>Do we want a forum ? </p>
