If it’s not a famous book, you may find some Goodreads reviews and if you’re lucky a Reddit post or two, but not vasts amount of online discussion like you’ll find about any passingly good series or movie.
And if you love a movie or a tv show, it is much easier to convince people in real life to also watch it, since it’s way less time consuming and not everyone even reads books, but most people watch movies.
I just think that this really sucks about reading books.
Yes. Just like I don’t feel the need to monetize all my hobbies (because then they aren’t hobbies they are jobs), I also don’t need to socialize all my hobbies. I do some things just for myself. I walk in the woods almost every day and that’s lonely too but I don’t think anyone would question that loneliness as a bad thing
(Well, to be fair, I do have my dogs with me in the woods. But usually I also have my dogs with me when I’m reading.)
