Del.icio.us has added a Facebook application for you to display your recent bookmarks on your Facebook profile and show a summary of your bookmarking activity in your mini-feed.
The application is easier to add directly from Facebook as opposed to adding it through del.icio.us. You'll also need to return to your del.icio.us account in order to change settings for this Facebook application. You can get the top bookmarks from the hotlist on your Facebook app, or you can insert your own username in order to get your own recent bookmarks. Others that view your profile will be able to see and access these recent bookmarks. Unlike most other Facebook apps we've seen lately, there are no links encouraging others to sign up for their own del.icio.us account as well.
