I'm excited about this news as an author. I am looking forward to seeing how the bookselling/reading business will function here. I once shared a book chapter-by-chapter here, and it was well-received. Sharing books in one piece and get them curated/distributed would be fantastic. But I guess the licensing matters of book content in such addition will need to be considered. I think self-publishers will have it easier than traditional publishers to share their books that way. Oh, wow, quite many questions appear now. ;D
Super, super curious, and excited!
All the luck and success to the team who works on this addition!
