I'm aware of Goodreads but would be interested in recommendations for where to go for book recommendations, across categories. Certainly there were many articles and lists of books from the end of the year, but I'd be more interested in discussion forums.
I'm not entirely adverse to advertisements, but more interested in what books people suggest and discuss online. Tastes vary, of course, and algorithms have their place as well (or AI if you prefer).
To take one website at random: the Gutenberg press. In theory a fantastic idea. Yet whenever I've looked at their website it's just a needle in a haystack. I'm sure they have an official blog or announcement system, but I'd be more interested in discussion or review. Not specific to the Gutenberg press, again, conceptually interesting, but just looking for things to read.
(I'm a bit Kindle-centric having drunk the Amazon DRM kool-aid, so that would be my preference for focus should that be an issue.)
