8. Updating the Profile
Although Facebook has shifted to the stream as the source of what a user is doing, the profile still provides a snapshot into who a user is and what she finds important. Applications can supply profile boxes, application tabs, and info sections that add to this information.
This chapter goes over the constraints and benefits of each profile box type and then shows how to create and update them. The Compliments application will be updated to use each profile feature. We also discuss how to use manage the Facebook cache for Facebook Markup Language (FBML) and images.
