Socialight has created a way to geotag your Facebook photos. Make a "sticky" from any of your photos on Facebook, add a description and some tag words, and mark it on the map. You can opt to show your socialight stickies on your Facebook profile as well. Stickies created on socialight's service will be included in your existing stickies with its Facebook application, as well as on your profile. It would be cool to stream or offer the option of clicking through stickies on the profile widget. You'll need to register with socialight before using this app.
Goodreads has made an online library to be added to your Facebook profile, letting you view books from the Goodreads website, as well as those that have been reviewed by your Facebook friends. Those books that you've added to your own list will show on your Facebook profile, but only after you've manually refreshed your Goodreads list through the application's homepage. Other than rating a book, nearly all of the applications functions will redirect you to to the Goodreads' main site.
CNET's Facebook app lets you search and browse through all kinds of gadgets and games, mark which ones you want, have, love or hate, and leave a comment. These will be saved on your list, which can be viewed by yourself and your friends, and can be modified by you as well. Your list will also show on your Facebook profile, and will feature the item most recently added, while showing smaller views of the rest of the items on your list. There is the option of manually selecting which list item will be featured on your profile (similar to indicating which photo you'd like to show as your Facebook album cover).
