I put in The Foundation by Isaac Asimov, The Test of the Twins by Margaret Weis, and On Libert by Mills. I got back a collection of literature by women of color and books about colonialism. I had no idea my book preferences were so conservative.
I'm not sure it works well for fiction. I put in a few different sets of science fiction works ranging from Heinlein to Atwood and it returns about half comic books, a significant number of fantasy/sci-fi works, and a smatter of other things. Oddly, it includes children's books I've read to my kid.
My bubble very much includes both Dune and The Far Side and I'm not certain how these are supposed to be in different bubbles. Are most Dune readers snobs who wouldn't stoop to reading a cartoon?
I think in this case it probably ends up suggesting random books that were read by your 'cluster' at different periods of their life (i.e. when they were a child) that they may not necessarily like to read now (I loved this book when I was a kid: 5 stars)
