With a few exceptions, I only read fic for specific pairings in all my fandoms, and I usually just join those comms. I also belong to a lot of fic challenge comms and my last resort is trolling through the mess at ff.net. I occasionally read fic recs, but those can be sketchy for me. It's not that I don't trust the people doing the reccing, but I like/dislike specific things and don't want to read just anything.
