Social Bookmarking URLs?

[desktop]

What I'm trying to do is find some more URLs for other social bookmarking sites. For example, here is the one I have for DesignBump....

<a href="http://designbump.com/node/add/drigg?url= <?php echo get_permalink() ?>&title=<?php the_title(); ?>" title="Bump This!" target="_blank"><img src="/img/design-bump.png"></a>

I'm wondering where I can find others like this so I can add a few more to my Share This box at the end of my posts. I have this hard coded into my PHP files so if I could find the URLs with the PHP codes then that would be awesome.

I anyone knows where I could locate these types of URLs please let me know.

Thank you.
