I've never posted in here, so I don't know how active it was in the past. I just added my current book to the What are you reading? thread.
I had a similar experience (shock at lack of posts) with the Book Club thread in the Author Lounge earlier this year. For a challenge that has been around as long as it has, it has very few contributions. I'm sure there are lots of people who read here...I guess many of them just don't post about it or write quizzes about the books!
