If you are interested in sharing book recommendations with other, or just manage your books, then bookwyrm is great for that! The .world team also has a bookwyrm instance up and running at bookwyrm.world with a community here on lemmy as well at !bookwyrm@lemmy.world. Read Ruuds original post about it here: https://lemmy.world/post/5904792
If you want to join another bookwyrm instance, then head over to joinbookwyrm.com.
Anyway, it’s a great place to find books, share books, and find people with similar interests in books! If there is anything that you feel needs to be improved or changed on the bookwyrm.world instance, then contact me!
EDIT - Mastodon account for the instance: @bookwyrmworld@mastodon.world
By free software you mean the FSF or OSI definition. Many people won’t care, and some of us actively are against corporate leech on free software, which this license helps with.
Does it though? As far as I know, there hasn’t been a legal dispute over this license before in a court. It probably wouldn’t even hold up in court with its oddly specific cases and vague wording.
