September 6 - 12: Discuss Part I, tagging each tweet with #1b140_1
September 12 - 19: Discuss Part II, using #1b140_2
September 19 - 30 Discuss Part III, Epilogue, Afterword, etc., using #1b140_3
We are a little less worried about spoilers in a work of non-fiction. That said, Rebecca has cautioned me that there is a big reveal in Part III, so please be careful not to reveal crucial plot points when discussing the book. As always, lead your tweets with the appropriate hashmark (#1b140_1, etc.) This way people who haven't reached that point in the text know to skip past your tweet.
Finally, I promised we'd branch out into Google Plus this month. This really involves nothing more complicated than posting a remark to your G + network, making it public, then tweeting the link to all of us on Twitter. I've gotten the ball rolling today with my own G+ post.
