For me, the holidays usually result in worse sales. If you're doing a rapid release model such as Timothy uses, it may not make as much difference because fans are primed to expect new releases at relatively regular intervals. But for those of us who can't match that pace, people's minds are elsewhere on the holidays.

I would consider releasing your book in early January. I find sales are worse during all holidays, unless your book is targeting the holiday itself.

It used to be that January was a gold mine for Indie writers. Everyone got their kindles and went looking for ebooks to fill their new readers with. But, there's quite a few more books available now. Times have changed and I don't see a rush of sales in January, but I always see a drop in sales on holidays (I even see less sales on weekends with my books). Usually, I still fare better in January.

My latest book took me longer than expected to finish, so it's pushed itself into the holiday season. The book is not themed for the holidays; it's sci-fi. Historically my books haven't done so hot in December so I've been thinking of pushing the release until January. I'm only releasing an ebook for now, which makes buying the book as a gift less likely. I might have more luck if people buy new Kindles or have gift money after Christmas. I don't think I can compete with the ad spend of others, especially since this is the first book for a new pen name. (I'm not sure I want to bother with ads at all with one book)

Guess I'm curious if others have had more luck releasing before or after the holidays, and whether you ran ads.

That was probably the scariest thing I'll read all year.

I belong to the camp that believes AI could/does pose an existential risk to humanity.

Remember when cults like Heaven's Gate and Jonestown, while crazy and self-destructive, were at least well-mannered enough to keep their destruction to themselves rather than trying to force the rest of us to share in it?

Ah, I miss the good old days.
