If you enjoy the stories on this website, you might also enjoy these recommendations.

Q is my subjective impression of the writing quality. 3+ means the writing didn't bother me, 4 means the writing is a reason to read, 5 means it blew me away.

R is a crude measure of the /r/rational nature. 3+ means that the writing scratches the rational itch, 4 means I think /r/rational would enjoy it more than a normal person, 5 means I consider it specifically rationalist fiction.

U is how unique the story is. Basically, would you be missing out on something important if you didn't read it? 3+ means you might regret not reading it, 4 means some of its qualities are very hard to find, 5 means there's nothing else quite like it.
