My Facebook redesign took effect some time early this morning... and the only big 'surprise' (for lack of a better word) was the prominence of "Facebook Credits" in the new header. Three links (Home, Profile and Account) now sit persistently across the upper right of your Facebook experience. When you click "Account", it reveals traditional account links (ie settings, privacy and help) - but it also includes a link to "Credits Balance". Until now, this was relatively buried on Facebook (you had to peck through advertising or birthday gifts, etc). It is as much of a sign of what is a priority (the Facebook Gift Store) and what is coming (Facebook Payments).
Clicking the "Credits Balance" link takes you to your credits homepage... which will invariably look different once Payments is a bigger part of the experience.
