I wish there really were algorithms that help you discover books and movies you'd like, instead of glorified ad-generators that roughly approximated your taste in genres. I just read Samuel Delaney for the 1st time, and he's incredible- wish I'd found his work ages ago.
I strongly recommend Stars in My Pocket Like Grains of Sand. But, be warned, the planned second book was never written, in part bc of the AIDS crisis changing the author’s ability to write joyfully about certain kinds of sex.
