Ah but this is what Adda is about
Very interesting concept, and a great solution, Nir Eyal. Finding a topic to discuss will need that you find the topic and you find the like minded friends to gather and discuss. In Bengal, we have a simple solution for generations, very much along the lines you described, we call it আড্ডা (pronounced “adda”), works very similar to your kibbutz. Interesting you found it out the hard way, :-); Addas are spontaneous, fun filled. There is no set topic to start with, you can start with anything really. But addas often go deep, and there are couples, but also other friends who chip in. Pray tell us more about your experiences.
