WordPress by default displays the comments in the order they were entered. What this means is that the latest comments are always at the very bottom of the section. I like to have the latest comments shown first.

Open the comments.php file contained in the currently active theme directory

look for the following code

<?php foreach ($comments as $comment) : ?>

replace it with

<?php
$comments = array_reverse($comments, true);
foreach ($comments as $comment) :
?>

And that piece of code does all the magic.
