Apparently this has ability has been built into wordpress for quite some time but a friend of mine recently pointed out that it can be done (pfblogs popular posts added to sidebar.) Here is the wordpress codex for this feature: http://codex.wordpress.org/Function_Reference/fetch_rss.
To add the latest perfume post to my sidebar I added the following to my theme…
<h3>Latest Perfume Posts</h3>
<?php // Get RSS Feed(s)
include_once(ABSPATH . WPINC . ‘/rss.php’);
$rss = fetch_rss(‘http://www.perfumebloggers.com/feed’);
$maxitems = 10;
$items = array_slice($rss->items, 0, $maxitems);
?>
<ul>
<?php if (empty($items)) echo ‘<li>No items</li>’;
else
foreach ( $items as $item ) : ?>
<li><a href=’<?php echo $item[‘link’]; ?>‘
title=’<?php echo $item[‘title’]; ?>‘>
<?php echo $item[‘title’]; ?>
</a> (<?php echo $item[‘dc’][‘creator’]; ?>)</li>
<?php endforeach; ?>
</ul>
