Actively working on https://thatbook.club (https://thatbookclub.com). An idea I had for me and my friends, and which we have been using for the last 2 years privately. Just made it open for others to join in. Similar to goodreads and other book clubs, but focuses on making logging pages and statistics around your reading more fun. Nudging friends when logging pages is the main motor behind this.
