Looks like Reading Weekends are becoming popular. The School of Life have run them too. There is an interesting difference though, between what we did and what they are doing. They have specially selected "books that will change your life" and Burkeman and Berthoud (a psychologist and a writer) who play the role of 'expert guides'.
On The Praxis Reading weekend people selected the books themselves, for any reason they like and the conversation was emergent. There was no expert, just a conversation amongst equals. So, the same, but different.
