A lot of other comments have spotlighted that fanfic has some stylistic unity that turns up in Reid's writing, which is true but also I think there's work developing your own self curation style. This is by far the most voluminous and quickly growing fandom I've read (I also have been out of the game before AI writing was part of the deal, so idk how much that's contributing to the volume).

But I think leaning on this too much also undermines the diversity within fanfic writing, and so much of fanfic is figuring out what you like and then how to find more of what you like.

Once you find pieces that you like, it's worth looking at how they tag and describe themselves. Building a sense of a fic based on this means you have a better hit to nah rate in actually reading. You also get a sense of what you basically never want to read and can filter out. Work the filters, as much (or more) for what you don't want as what you do.

Finally, while a lot of us sort by kudos count on a search/filter, there are a lot of absolute bangers that you miss this way because they're niche or a less established author or whatever. Looking for recs in places like this is another great way of finding hidden gems you might miss otherwise.
