“Has No Friends”: Amazon Is Keeping Amazingly Detailed Records on Its Customers and They Are Downright Insulting: Here's how to check yours.

Some of the records they have are silly. Ie: likely owns x router (well duh I just purchased it). But some are odd - “can touch type without looking at keyboard”. How did they figure that out?

About they track the time between key inputs when you’re searching for something. God knows why though I can’t imagine it being particularly useful information.

How they got that observation makes sense. There must be some assumptions about that then - like that perhaps I’m more tech savvy than most people (apparently 20% of people can do that), or perhaps I make more money than average and my prices should be higher. That’s probably it.
