Added the Simple Tags plug-in, so now I have a tag cloud and a related posts display at the end of each post. I also have a “This post is about:[tags]” display at the end of the posts, and words in my posts that are tags are automatically linked to the appropriate tag page.
Because it’s no longer necessary, I removed the following code from theloop.php (at Synthesis):
<?php /* Tags */ the_tags(__('in ','k2_domain')); ?>
