You could go over to the Fediverse and join BookWyrm. One server that is a BookWyrm instance is
https://ramblingreaders.org, for example. Or if you have a Mastodon account, you can follow BookWyrm accounts there. I don't use it myself, but I see it getting a lot of action.
Just don't expect anything in the Fediverse to act like the algorithm-driven apps from the big companies, it is literally a different world.
