I’m using LibraryThing, after fleeing GoodReads a few years back, and I just learned about BookWyrm. I’m interested in what others apps and sites are out there for keeping track of your books and/or to-read list, and/or reviewing and/or discussing them, and what folks think about them.
I left GoodReads because I try to have as little to do with Amazon as possible. I tried StoryGraph but never warmed up to it. I realize LibraryThing has some indirect Amazon ownership, but I found it an acceptable compromise.
