Not sure if anyone knows this or not but my main criteria for reccing a lot of stories is if I'm able to finish reading it. (as in it kept my interest enough to finish) The instant recs are the stories where I can't stop reading until I reach the end.

I did not know this is how you make recs - thanks for sharing. There are a lot of enjoyable fics on your list I might never see otherwise,so I appreciate it.
