I want to replace Thematic's comments with Facebook Comments. With a child theme it's really easy, just add a file comments.php that looks like this:
<?php thematic_abovecomments() ?>
<fb:comments href="<?php echo get_permalink($post->ID); ?>" num_posts="10" width="530"></fb:comments>
</div><!-- #comments -->
<?php thematic_belowcomments() ?>
BUT, I would like to accomplish this with a plugin. Anyone know how I could override the parent's comments.php with a function instead of a template?
