This is my first wordpress hack, so be gentle. :)
wp-recent-links is a hack (soon a plugin?) for adding a links blog to your WordPress-powered site, similar to kottke.org's remaindered links. Compared to WordPress' included links manager, this plugin allows you to have a separate archives page for your links blog, including monthly archives.
You can see it in action on my site, it is labeled "Recent Links" on my sidebar, with its own archive page.
