How do you add your Facebook friends to Twitter?

Simply invite your Facebook friends to follow you on Twitter. Just make sure your post has the correct setting for distribution. The control for this is near the 'Post' button. Hope this helps. P.S. I don't think you can add followers on Twitter, if that's what you meant by your question - only your friends can initiate following you, not vice versa.

To connect your Twitter account and your Facebook profile:1.Log in to the Twitter account you want to associate with your Facebook profile.2.Go to your Settings menu's Apps tab.3.Click Connect to Facebook.4.If you are not already logged in to Facebook, then you will be prompted to enter your Facebook login credentials. Enter your credentials and click Log in to sign in to Facebook.5.You will then receive a prompt explaining that Twitter will receive certain information from your Facebook account. In order to continue, you must select “Okay.”6.You will then be prompted to select the privacy settings for who will see your Tweets and Retweets posted to your Facebook wall. It is set to friends by default.7.Click “Okay” to complete the process.8.Your Tweets and Retweets will now post to your profile Facebook wall and your username will be displayed there as well. @Replies will not be posted.

- Now you need to head on down to the Twitterimporter. You can find this by clicking on the previous link, or by clicking on Discover then Find Friends on the left navigation. Click on the Search Contacts button by the Yahoo! Mail option.
