       Welcome to SciPost's Ontology, which is a curated set of interlinked Topics
       pertaining to all of the sciences.
     </p>
     <p>
       Topics and their relations are defined by Editorial-level personnel.
+      The ontology is used at many levels within SciPost, including but not limited to:
+      <ul>
+	<li>identifying the best potential Editors-in-charge for incoming submissions</li>
+	<li>identifying thematic areas for which the editorial workforce should be increased</li>
+	<li>providing Editors-in-charge with referee suggestions</li>
+	<li>giving readers a way to identify interesting published content</li>
+	<li>assist our internal metadata- and content-driven engines</li>
+      </ul>
