Like GoodReads, but tired of Amazon? BookWyrm might be what you're looking for.
Old, but just in case folks don't know about this...
EDIT: I was stunned at all the upvotes this got, and from a two-year-old article to boot! I hope I didn't do anything to overload their servers. When I posted about the Instagram/Pixelfed import tool, I was kind of surprised at how many folks that were on Lemmy didn't already know about Pixelfed, which is why I posted this, also from We Distribute. For a long while, IIRC, the Fediverse pie chart was taken up almost entirely by Mastodon (which it probably still is) followed by a small but visible sliver of Pixelfed--Lemmy hardly registed at all. Just goes to show how fast we've grown!
EDIT EDIT: I see that some of you were a little bit disappointed with BookWyrm, but I hope you will stick with them because I think they can be an important member of the Fediverse. The sense that I get is that they're stretched very thin, and could use some support, monetarily of course, but especially from other developers.
I signed up a few days ago. I never used GoodReads much. Last activity I had there was in 2013 and I kinda fell out of the habit of reading. But I picked up a book this week (and finished it in two days, haha), Recursion.
It let me import my GoodReads data and I've been slowly adding books to read to it. I think for me, the mental hurdle I had was the paralysis of choice. I decided to just pick a sci-fi book that was available for instant borrow on Libby and go from there. I currently started The Big Door Prize because I loved the first season of its TV adaptation. Happy to be reading again.
I feel that choice paralysis a lot. My reading moods fluctuate, so sometimes I want to read one genre or sometimes another, but I also have a massive TBR so I struggle determining what book I should read. I've learned to just let myself start something, and if it doesn't work out, then I can stop and maybe pick it back up later. For instance, I just finished Prince of Thorns by Mark Lawrence, a book that I had tried to read three times prior. This was the first time my interest stuck, and now I am finishing the trilogy. But getting over that initial hurdle of "what should I read" can be difficult.
