I had about 200 Buffy fanfics bookmarked when it was my central fandom and then when I did my last computer swap I deleted them all. A number of them were no longer valid links and I realized that I already had a backlog of SPN fic I had bookmarked as well and would probably also never get around to reading. So a corollary may be that more fiction will disappear than one ever has time to read either.
