Yes I have done something similar on a bigger scale. I’ve participated in a reading/discussion circle that spanned about 200+ people in different countries. We’ve all read a philosophical book and there were cards that had most of the chapters’ contents on them, so you didn’t necessarily need the book. We were encouraged to find a reading partner close by to discuss a chapter per week. I still meet up with my reading partner regularly even months after the project ended.
It was the only way I would have worked through the complex book. I wouldn’t have done it alone.
