Fictional Fans

\o/

Although I don't have any specific recs to offer, in light of your post I should mention that buffyversetop5 is a seasonal recs community that has been running since 2005, so there are a lot of Buffyverse (and a small number of other Whedonverse) fanworks that have been recced there. There are a lot of tags to check out and one can also use the search box there to look for specific things.

There's also an AO3 collection that is still in progress but has hundreds of works in it already: https://archiveofourown.org/collections/buffyversetop5
