Using the SocialToo Status application, you can share your personal status from Facebook to your personal news feed, as well as Twitter.
If you are already a SocialToo user, go to http://www.socialtoo.com and click the "Facebook App" link to activate SocialToo Status. Once the application is enabled for your account, you will see a SocialToo Status icon in the "attachments" section of Facebook, which you can update from the home screen, or your personal profile. If you have already associated your Twitter account with Facebook, it will ask for permission to publish, and following this, you're all set. You can even grant the application permission to publish from fan pages you may run as well.
If enabled, my posts from Facebook can flow to Twitter as well.
For a long time, power users of social media tools have found ways to bring their Twitter updates into Facebook. But now, you're seeing the first tools start to take data the other direction. You can also find the SocialToo application on Facebook here: http://apps.facebook.com/socialtoo/status.
