I just finished reading book 9 of the Destroyer series on my Kindle. From inside the book, I clicked to go to the Kindle Store, and my recommendations were:

• Six Easy Pieces, The Pleasure of Finding Things Out, Perfectly Reasonable Deviations, and Six Not-So-Easy Pieces, by Richard P. Feynman
• Bad Astronomy, by Philip Plait
• Genius, by James Gleick
• The Faith Healers, by James Randi
• The Varieties of Scientific Experience, Pale Blue Dot, and Billions & Billions, Carl Sagan
• Japanese Hot Pots, by Tadashi Ono & Harris Salat
• The Destroyer volumes 7, 6, 12, 3, 11, 17, 40, 31, 36, 37, 27, 44, 35, 34, 43, 30, 42, 26, 45, 39, 33, 20, 25, 49, 48, 46, 32, 38, 29, 47, 41, 28, 55, 50, 53, 52, 51, 57, 54, 56, and five more un-numbered books related to the same series by Warren Murphy and Richard Sapir.

All praise for filling the list with things I’m actually interested in, but do you think maybe you overdid it a bit on the Destroyer novels, especially since the one I’m most likely to want right now isn’t on the list at all?

At a guess, the metadata simply isn’t up to the task of identifying series relationships, and I’m seeing the usual “you just bought a nice watch, so you must be interested in buying a dozen more nice watches” problem.

Also, while I’m pleased that I finally have my Kindle recommendations straightened out, I sigh in despair at the weeks of Android-app-recommendation cleanup I face after buying some apps for my Sony Tablet.

[Update: it seems book 10 is the only one in the first fifty or so that isn’t available for Kindle yet.]
