   How would I go about this? I've tried using get_the_tags(), but while I can set up the PHP correctly to cycle three times, it seems I can't actually access the data...

   $tags = get_the_tags(); if ($tags) { for ($i=0;$i<=2;$i+=1) { echo $tags[$i]->name . ' '; } }

   From the Codex example at get_the_tags
   

   <?php
   $posttags = get_the_tags();
   if ($posttags) {
   foreach($posttags as $tag) {
   echo $tag->name . ' ';
   }
   }
   ?>

   Or look at get_the_tag_list.

   I'm pretty sure that both of those suggestions will display all of the tags.

   Sorry missed the goal ;)
   

   <?php
   $count = 0;
   $posttags = get_the_tags();
   if ($posttags) {
   foreach($posttags as $tag) {
   $count++;
   if ($count <= 3 ) {
   echo $tag->name . ' ';
   }
   }
   }
   ?>

   Is it possible to do this but also make the tags links to the tag archive?

   Yes: use get_tag_link().

   Where would you use that? Inserting it in place of get_the_tags() breaks the code.

   This should do the job:

   <?php
   $count = 0;
   $posttags = get_the_tags();
   if ($posttags) {
   foreach($posttags as $tag) {
   $count++;
   if ($count <= 3 ) {
   echo '<a href="' . get_tag_link($tag->term_id) . '">' . $tag->name . '</a> ';
   }
   }
   }
   ?>
