Caveat: I am very new to the Twitter world, and it’s still fairly overwhelming to me. I do not use Twitter for book recommendations because there are simply too many of them. I might look twice at a book recommendation that is the same genre I write in. However, until I felt like I actually have a sense of the taste of the people I am following on Twitter, I probably won’t follow up on book recommendations. So, book recommendations might be great if I knew the person (or was aware of their work) before I started following them on Twitter but probably not if I only became aware of them through Twitter.
