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 use LibraryThing to keep a record of what I own (the barcode scanner is particularly useful), and TheStoryGraph to track what I read because I’m a sucker for stats and graphs.
I hadn’t heard of BookWyrm before joining this community but it looks interesting.
