I got an empty red bar and, when I clicked on it, it said "error." This doesn't seem very personalized. I mostly read textbooks and the closest genre match is "nonfiction," which is pretty broad, and if that's all I get to select, I'm guessing you're going to show me puff-piece crap by ex Navy Seals and ultra endurance athletes that top the best seller lists. Not exactly what I'm looking for. Personalized implies it would recommend based on what you've read and enjoyed in the past.
