I've noticed that code snippets do not get syntax coloring like stackoverflow. Instead the whole chunk appears black and white. Is it something I've done wrong or is this a massive missing feature?
This is probably a server-side issue. On StackOverflow, code snippets in questions or answers have a special
prettyprint class, eg.
<pre class="lang-c prettyprint"> ... </pre> whereas on Gamedev the code snippets are served as
<pre><code> ... </code></pre>.
Code will now be styled by default - look here if you need to manually override a specific syntax.
