The "Why write reviews" important link (https://www.writingforums.org/showthread.php?t=4705) goes to an empty forum. Is this a Taoist riddle to make me rethink my concept of what it is to review?
It is a known issue. The post was lost a while ago due to a software defect. The site owner will attempt to restore it from backups when he has the opportunity. Restoration is preferable to recreating the post from scratch, because there are literally hundreds of links to that particular post.
