Platonic button

I just realized that all the books that Amazon recommends for me are business books varying from crappy to somewhat respected. I was a bit shocked until I realized that I have been scouring this genre to search inside the books to verify bibliographic data for my job.

What if I want to see recommendations for books I actually want to read?

I propose a "platonic button." When I'm going to Amazon for strictly professional reasons, I click the button. Then when I'm done, I can click it again, assuming my next search is for something I would be genuinely interested in.
