You're onto something with Snarry that ultimately doesn't work out. While I don't have any fics like that, I have to say that rec lists are still around, in a way... They've just transformed into individual recs dispersed here and there (following fandom itself). Comms like one-bad-man and platforms like Reddit and Tumblr have a bunch of recs, only they aren't as long and organised as old school rec lists. I think if you and I, for example, went back and streamlined our blurbs, we could easily build rec lists for fic we've enjoyed.
