Delicious is a social bookmarking service that allows users to tag, save, manage and share web pages from a centralized source. With emphasis on the power of the community, Delicious greatly improves how people discover, remember and share on the Internet.

Lots of people use Delicious to store bookmarks online, and as a blog publisher you should want your readers to be tagging your posts there. Luckily for you, it’s ridiculously simple to give your blog’s visitors a quick “Add this to Delicious” link.

Just add this code to your single.php template and you’re done:

Bookmark on <a href="http://del.icio.us/post?url=<?php the_permalink() ?>&amp;title=<?php urlencode(the_title()) ?>" title="Bookmark this post on del.icio.us">del.icio.us.</a>

Tip: Use &amp; instead of just & so that your HTML will be valid!
