Here’s another aspect of the ebook reading experience Amazon has a monopoly on, and somehow lacks a vision for. From The New Stateman:

Goodreads today looks and works much as it did when it was launched. The design is like a teenager’s 2005 Myspace page: cluttered, random and unintuitive. Books fail to appear when searched for, messages fail to send, and users are flooded with updates in their timelines that have nothing to do with the books they want to read or have read. Many now use it purely to track their reading, rather than get recommendations or build a community. “It should be my favourite platform,” one user told me, “but it’s completely useless.” […]

With the vast amount of books and user data that Goodreads holds, it has the potential to create an algorithm so exact that it would be unstoppable, and it is hard to imagine anyone objecting to their data being used for such a purpose. Instead, it has stagnated: Amazon holds on to an effective monopoly on the discussion of new books – Goodreads is almost 40 times the size of the next biggest community, LibraryThing, which is also 40 per cent owned by Amazon – and it appears to be doing very little with it.

To improve discovery I would focus on manually curated lists, like bookshop.org and fivebooks.com do, and instead of giving users a meaningless star rating I would aggregate book reviews. bookmarks.review, a sort of Rotten Tomatoes for books, does just that.
