We've spent some time lately enhancing our Facebook Application to make it work better with Facebook's new interface. Notably, you can now add FriendFeed as a tab to your profile. Just click the "+" tab on your profile page (to add a new tab) and choose FriendFeed.
If you haven't already, add the FriendFeed Facebook App to share your FriendFeed activity with your Facebook friends. We're continuing to work on some additional changes, but do let us know what changes are on your wishlist in the FriendFeed Feedback room.
