Blizzard has launched a Facebook application that allows you to link your WoW account to Facebook and import stats from 10 of your characters. You can spam up your friends with the automatic posting feature (which I highly suggest you TURN OFF) but you can also make pages and share some awesome WoW info. If you're a regular on Facebook then this might be just the thing for you.

Share your proudest in-game moments with your real-world friends online with the new World of Warcraft Armory application on Facebook. The app lets you create a custom feed of your characters' activity straight from the Armory, share it with the Facebook community, and view your friends' characters — all on Facebook. Once you’ve set up the app and linked it to your account, your Facebook identity will be associated with up to five characters of your choosing, and the app will generate automatic updates for your accomplishments, such as level gains, achievements, boss kills, and so on. For more information on how the app works, along with some helpful privacy tips, check out the FAQ.
