By reading a book and discussing the matters in an informal and friendly atmosphere, more people would feel like talking. In particular this is an issue with women that are not normally at ease in talking in front of men. Not all the participants to the discussion have to have read the book. But this kind of setting encourages more people to read.
The culture of reading with the social media in place and TV culture has almost disappeared.
The book club will encourage more people especially women to read more and improve their own knowledge and also find the courage to talk in front of groups of people. One angle of this forum is to capacity build some people and ensure they improve their reading, speaking and analysis skills.
