Overall, I enjoyed the experience of reading chapters with other people and discussing them. What I liked the most what seeing the different perspectives that everyone had.

I'm not sure what improvement could be made, it was done properly but the participation rate dropped as the chapters went on. Maybe showing who's currently reading the book will encourage others to join in and keep the pace.

I'd personally go for The UNIX Haters Handbook because I've never read it thoroughly, always skimmed through it.

Thanks again for organizing this, it's very fun!
