+
+    <h2>Why?</h2>
+
+    <p>I like reading stuff on the internet that is of interest to HN voters,
+    even if the HN administrators think it's off topic and don't want it on
+    the frontpage, which is a decision I respect.  Again, their site, their
+    rules.</p>
+
+    <h2>How?</h2>
+
+    <p>Go and the
+    graciously provided <a href="https://github.com/HackerNews/API">HN
