But it doesn't. However, the folks at Much-Ado.Net have created the Austenbook which does. The full text of Pride and Prejudice is told in facebook updates with hilariously clever results:
Lydia Bennet and Kitty Bennet have joined the group 1,000,000 Strong Against the Officers Leaving Meryton!
Lydia Bennet is going to Brighton with Colonel & Mrs. Forster!!!!1!
As funny as it is it reminds me of how normal it is to post every intimate detail of your life on facebook in a means of typed moral support. Ah the modern age, no wonder romance is dead!
