<p>We can encourage community members to formulate and post appropriate questions on the next paper a week or two beforehand.  This would serve to clarify ideas and perhaps interest more casual users of the site in the JC activity itself.  For example, questions about bagging and random forests could have been (and still would be!) of interest for the last JC (what are they, how do they compare with other methods, are there salient examples of their use in the literature, what software is available, what do you need to know to use them effectively, what advances have been made since Breiman wrote his <em>Two Cultures</em> paper, and why do they work?).</p>
