<p>My vote would be for <a href="https://stats.stackexchange.com/q/11659/1036">Essential data checking tests</a>.</p>

<p>The pertinence of the topic to this community I think would be obvious. So for a few other reasons why I think this would be a good blog post:</p>

<ol>
<li>Its non-technical nature makes it accessible to a wide audience.</li>
<li>I think it would be of interest to a wider audience across the stack.exchange sites, and so would be a good platform to gain stats.se some exposure to members of other sites.</li>
</ol>
