I've received a bizarre amount of "Who's It For?" summaries that use the word "riven" which isn't a particularly common word and thus keeps throwing me. I'd say I'm seeing it about 30% of the time when I look up books.

Maybe this is just a complaint, but the word isn't always being used correctly either. I don't know how you manage the LLM which generates those summaries so I thought it might be worth pointing out. I have started screenshotting every encounter I have with this phenomenon in case you'd be interested.
