MyLists allows you to create simple lists and share them with others.

Zoho: You can add Zoho to your Facebook profile; this gives you the power to write all your office-ish documents.

Social bookmarking and networking

Update your Twitter status from Facebook with Twitter for Facebook.

Media

Create your own personal multimedia channel - podcasts, videos, documents, pretty much anything - with SplashCast for Facebook. For example, I was able to find the last 30 or so NPR programs and tweak them into one long-running show - you can also use this to create presentations from .ppt files on your machine and share them with others.

Editing

Edit photos from within Facebook with the Picnik application. You can edit photos from your own 'puter, the Web, Flickr, Picasa, etc.

Use Picasa within Facebook with the Picasa app; you can upload photos, resize them, share images, and more.

Some other interesting ones are

• (fluff)Friends. This application lets you put a fuzzy pet on your profile that your friends can feed and pet. You need "munny" to buy food for your pet, and you earn it by petting your friends' pets. Horrible. But three people mentioned this application to me.
• Scrabulous is Scrabble in Facebook. Scrabble is a great social game. Facebook is a great social directory. This is a great idea.
• E-mail Me Instead, aka Xobni, is a little application for old folks like me who still like e-mail. It gives your profile visitors a quick way to drop you an e-mail, so you don't have to communicate through Facebook.
• Appsaholic is a Facebook ranking service. No surprise that it was popular at the Facebook HQ. It shows which applications are getting traction, and displays nice charts and graphs of usage
• Graffiti. If installed, this lets friends deface a small area of your profile page. Most people who mentioned this application didn't like using it, since they found it hard to create good-looking tags on other peoples' pages, but they kind of still liked it on their own pages.
•  Finally, Flixster is a group movie rating site. After you rate a bunch of movies, it tells you which of your friends you are most compatible with--at least as movie buddies.
