Apparently there’s a new ereader on the market, Glose, which adds a bunch of social/sharing/discussion features to ebooks.
I haven’t actually used the app, though I did download it. The selection of books is pretty strong but, of course, none of the books you’ve bought from other sources will work within Glose, and you can’t (that I can see) import books from a non-Glose platform into the app.
I also think the discussion/annotation stuff is all public. Which… is just such major facepalm.
One day, tech bros will learn.
One day, not today.
