I have set up a librarything account. I look forward to adding titles. I was going to include reviews of books I knew well, but then I realized that the reviews wouldn't matter so much in this database. As a librarything user I wouldn't need to read one person's opinion of a book. I would rely on the wisdom of crowds and see what hundreds of other people with this book have chosen to buy. The sum of many simple decisions tells me as much or more than one well-considered opinion.
