The code above didn’t work for me (on version 2.8.4), sorry simon. Instead, I used this and it worked:
<?php query_posts('category_name=articles&showposts=5'); ?>
<?php while (have_posts()) : the_post(); ?>
<div class="post" id="post-<?php the_ID(); ?>">
<h2><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>"><?php the_title(); ?></a></h2>
<p><?php the_time('F jS, Y') ?> <!-- by <?php the_author() ?> --></p>
<?php the_content('Read the rest of this entry »'); ?>
<p><?php the_tags('Tags: ', ', ', '<br />'); ?> Posted in <?php the_category(', ') ?> | <?php edit_post_link('Edit', '', ' | '); ?> <?php comments_popup_link('No Comments »', '1 Comment »', '% Comments »'); ?></p>
</div>
<hr>
<?php endwhile; ?>
The only thing I changed was using category_name=articles instead of cat=articles
