First of all, in spite of the fact they use the horrible phrase “the Pintrest of book discovery” even though many people have already created pinboards specifically for books, this PW article is a nice overview of Riffle, another stab at a discoverability app. (Full disclosure: the Riffle link is my referral link, and if you click on it, you’ll help me get an invitation sooner.)
Hopefully the above application can help people discover digital literary fiction. As this PW article points out, most if not all of the ebook success stories we hear about are in genre fiction, and sales of literary fiction are not growing along with the rest.
