I'm in as well!
Hmm, so it looks like each chapter averages ~40-50 pages (some slightly higher, some slightly lower). The typography/font size makes it look like there's potential for each chapter to be a quicker read than anticipated, though.
Maybe we could give people some time to sign up and secure their books (e.g., 2 weeks) and then organize things according to content? I'm sure some chapters will include topics that will warrant much more discussion than some other chapters. I'm thinking the more experienced UXers could help identify those; alternatively, we as a group can agree to read chapter X by a certain date and then decide from there how we'd like to divide up the discussion.
To break up the monotony, perhaps individual people (or pairs, mini-teams, etc.) can claim a chapter and facilitate discussion of them, based on individual interest. I also like @enlightened_06's suggestion to identify some elements a priori and then post our responses to those each time we return for discussion.
