Yasiv is a visual recommendation service that helps people to find the right product from Amazon's catalog. Being it a book, a movie or a video game - Yasiv finds anything what is sold on Amazon.com.
I played with it a bit. The attached image is centered on Goldratt's The Goal. The first cluster of books is obvious - Goldratt's other titles. The next clusters are interesting, leading into general management or to Lean.
I like that it's a different way to see recommendations than reading the list of recommendations that Amazon provides. It's fun to play with. I suspect this would be most helpful when looking for reading suggestions for my kids or gift ideas based on other gifts. I don't know how much I'd use it when I am shopping for my own books - I usually know what I want when I go there.
