With Paper, Facebook set out to prove that it could think small, rebuilding itself from the ground up for mobile devices. This meant removing lots of clutter, and in some cases, leaving out certain features that some Facebook users might have considered essential. Today, Facebook is launching Paper 1.1, an update meant to add back a few of Facebooks most important features, while continuing to think about how Paper can be different. Paper 1.1s most noticeable addition is the inclusion of Birthdays and Events, two of Facebooks oldest features.
