A well-written book which remains fun to read well after Google+ has died. Some UI and UX ideas in Google+ remain interesting today, others were incomprehensible, others were shrouded in mystery (such as the source of the personal data Google force-fed into Google+). It's hilarious how many pages it takes to explain the "circles" system. I had a Google+ account because Google forced me, but I didn't use it much, and I think I had never understood some of these finer details either. At least the author was honest in acknowledging it wasn't likely to matter.
