> Most people do not realise how much data Google et al. collect about them, and are genuinely shocked when it is shown to them (even though, yes, it's an existing feature well known to you and most HN readers).

I was surprised (even though I should not be) when I saw how conveniently all my Amazon purchases and travel plans (flight reservations, check-in, rentals etc.) were neatly organized when I went to remove all my personal information. I understand the convenience (with Amazon - being able to track the delivery, flights - automatic calendar scheduling etc.) but oh boy does Google like to gather all the data forever.
