Here's a tip that only an information geek would care about. If you've ever looked at my taxonomies, you'll know that I describe nodes by facet, e.g. file format, person, subject. Years ago, in another version of Drupal, I used to show terms applied to each node by facet, but with the upgrades and changes to the taxonomy module, I gave up trying to keep that up to date. Luckily, I found in the PHP-Template documentation, that someone posted a snippet for sorting/displaying terms by vocabulary. So I'm using this snippet to display my terms by facet again.
Here's a screenshot of terms in action:

Like I said, that's the kind display of metadata that only a info geek would want. But I think it also demonstrates to people new to Drupal the kind of description/categorization of content that might be useful in different environments, e.g. a corporate intranet.
So to do this, use the following code in your node.tpl.php (snarfed from drupal.org):
<?php if ($terms): ?>
<?php /* sort taxonomy links by vocabulary 27 */
$terms27 = taxonomy_node_get_terms_by_vocabulary($node->nid, 27);
if ($terms27) {
print '<div class="terms">Forums: ';
foreach ($terms27 as $key => $term27) {
$lterm27 = l($term27->name, 'taxonomy/term/'.$term27->tid);
print $lterm27.' - ';
}
print '</div>';
}
?>
<?php endif; ?>You would repeat that code block sandwhiched between "if($terms) ... endif" for each set of facets you want to display.
