Go to facebook.com/twitter and link your profile or page to your Twitter account. Once you link your accounts, your Twitter account will be updated every time you post a public update to Facebook. Only posts whose privacy you set to Public using your inline controls are eligible for this.

Consider this: Twitter’s 140-character blips don’t feel quite right on Facebook, which lets people post longer updates. Also, frequent Twitter updates are right in line with the ethos of the site, while they can be annoying on Facebook.

But going the other direction -- from Facebook to Twitter -- might be appealing if for no other reason than providing content for people who struggle to keep their Twitter stream interesting for fickle followers who can unfollow you on a whim.
