My SO got TikTok for this reason. There’s a big community on it for reviewing the latest fiction and YA novels. I suppose many readers aren’t looking for lengthy reviews when they choose what to read next, but rather a person suggesting related content to a genre they enjoy.
This is easy to understate, given how panned fiction and YA both are in other venues. Even Reddit's /r/books is (and long has been) absurdly stuck up when it comes to YA novels.
Dear YA prudes, remember that Heinlein and Asimov (and so many others) wrote books aimed at that demographic too.
Buying books doesn’t imply reading them (talking from personal experience)
I too have a "living" library haha
Not buying books doesn't imply not reading them (libraries!)
#BookTok is a fairly large community. Recommendations move needles. The Barnes and Nobles near where I live has a "Recommended by TikTok" section. Most of the people that read and talk about books (for enjoyment) reference TikTok to some degree. This isn't to say they are all content creators. Simply put, that makes as much sense as me saying "I didn't think users of HN read books."
