It seems Amazon has recently corrected a longstanding problem with its Kindle eBook store. For as long as I’ve been using the Kindle store, every nonfiction category, and all of said category’s descendent categories, have been mirrored under a collective Nonfiction category. This created a strange overlap, and bloated the category count up to nearly 7,000.
It appears that this has been rectified. The Nonfiction category still exists and contains the same child links, but they all point back to the top-level categories. This greatly improves the organization of the store, in my opinion, and trims the category count down to an almost svelte 2,800-ish.
Well done, Amazon!
