How do I publish entries from my feed to other sites like Twitter and Facebook?
Whenever you’re posting a message or a link using the text box at the top of your feed, there is a check box to “Cc:” Twitter. If you check this option, you will be asked to log in to your Twitter account. After that, you can choose on a per-post level to have your post show up on both your FriendFeed and your Twitter accounts. You can also configure additional options for publishing to Twitter—such as also publishing your comments or updates from other services automatically. For Facebook, you can add the FriendFeed Facebook application. The app will put your FriendFeed on your Facebook profile and in your mini-feed. You will also be automatically subscribed to your Facebook friends who are already using FriendFeed, and your friends on the two services will continue to be kept in sync.
