Sorry, but I really do. Every time I am searching for stuff on amazon it will have an effect on the start page. Articles that are similar to the search will show up. Regardless on how embarrassing they might be. I regularly search for gifts and I really don't want those guys on my landing page.
Thinking of buying a present for your girlfriend? Never open amazon when she is around you. Even if you bought the present a few days ago. Amazon will ruin the surprise and show related products on your start page. Even worse: if a friend sends a link to an amazon product as a joke, it will show up there, too.
I won't open amazon when other people look over my shoulder. Never. Because of that.
