one thing that readers often do, Dot, is to stick with "finished works", and in this fandom there are quite a number of them. Not every author abandons their work, but recently, I would say the past three months or so, many authors, whether it be personal disillusionment, quarrelling within the fandom, or the demands of real life, have stopped writing, abandoned their stories for something else, or found other things to do.
This does happen in the "published" world as well, an author will get an advance for a book and simply never complete it, leaving the publishers to pursue them for the advance money once the original schedule gets broken. That is an endemic problem with the creative arts, though I am sure it happens far more often in the amateur, unpaid world!
I will add, too, that there are a small number of works in the BBM fandom which were not completed due to legal pressure from lawyers for Annie Proulx. This pressure may also have scared away other serious fandom authors who were afraid of getting a lawyer letter. I myself got one, and my response was to rewrite my stories, and I am spending much of my energy rewriting and editing rather than cranking out new tales. But the ones I wrote, I finished. All nine books plus a number of stories. Works that were interrupted due to legal action were: Force of Nature, the sequel to the completed "Somebody New" by Jenna Sinclair, and "An Uneventful Life" by no_reins, a sequel to the completed "Riding Fence." The originals of these stories, like my former Laramie Saga, are no longer available in the fandom.
