This has been suggested before, a few times. Problem is people create threads for this and the threads don't usually last a week. Largely, i think, because people go in, name their books, and then don't have anything else to add. So the people interested enough to go in there run out of things to say quickly.
And easier way to go about this is to start your own private chat group. Or see if one already exists on the topic. To see which groups exist, and to make your own, go to the top of the page, select 'Community' and from the drop down click 'Chat Groups'.
