Produces output very similar to <a href="http://delicious.com/help/linkrolls" rel="nofollow ugc">delicious’s linkrolls script</a>, but in a way that isn’t guaranteed to mess with most themes.
Allows you to customize:
<ul>
<li>The number of links to display</li>
<li>Whether the link’s description is shown, if you provided one</li>
<li>Whether the link’s tags are shown</li>
<li>Whether the link’s favicon is shown</li>
<li>Showing only links with certain tags</li>
<li>And the ever-popular widget title</li>
</ul>
<h3>History</h3>
<ul>
<li>1.2.1: Bump the WordPress version and get rid of some legacy mentions of 
“del.icio.us”.</li>
<li>1.2: Update for the annoyingly backwards-incompatible nature of the new 
delicious.com design and v2 feeds api.</li>
<li>1.1: Allow multiple instances of the widget.</li>
<li>1.0: Initial release.</li>
</ul>

delicious-plus widget

Was a great plugin, but delicious have changed their API or discontinued the feeds or something, so it doesn't work anymore.
Edit: Found the solution. Just replace feed.delicious.com with previous.delicious.com in the PHP file.
