"Search and categories are complete garbage."
I'm consulting in the pet space, if you search for 'Mousr' which is the name of a very cool pet toy brand that they carry - you get PC mouses (ie 'Mouse'). Not the brand 'Mousr'.
So basically their 'spell correct' 'Mousr->Mouse' utterly and completely overrides the notion that the users wanted to in fact input 'Mousr' to get that product.
Instead, in order to find the product, you have to type the company name 'Petronics'.
FYI - if you've worked in NLP, you might recognize this problem: the edit distance from Mousr->Mouse is short, and the 'e' and 'r' keys are beside one another, and of course the word 'Mouse' is very common while the word 'Mousr' is very uncommon, leading the error correction algorithm to 'over correct'.
This is a problem in NLP where very uncommon things that are lexically adjacent to common things get suppressed.
Since 'Mousr' however, is 100% in the Amazon catalougue, you'd think they'd include it!
But no.
Consider the resulting 'lowest common denominator' approach: statistically speaking, it might be slightly more economically efficient to actually assume the error and show PC mice, besides, 'everyone' needs a PC mouse anyhow!
But the interesting, long-tail stuff gets suppressed.
This is to me the statistical epitome of not just Amazon, but of our new, globalized culture - the big brands have such power they just bulldoze through everything else - and the 'short run' economics are in their favour! They can point to 'the efficiency of the search' etc. to validate to everyone else in the equation (ie city councillors approving permits, banks giving loans, buyers - heck, even consumers) to validate their case on competitive, culturally secular grounds.
It takes quite some magic, a loyal following, a magic meme of attention, a super faithful investor, or deep rooted cultural behaviours (like Italians who could care less about the new 'Starbucks' because they already have good coffee).
Most big CEO founders have made some kind of 'big claims' or almost arbitrary statements about 'how it ought to be' and they stuck to their guns on those, I wish Bezos et. al. would think just one tiny bit about the 2cnd order effects of their businesses.
