Search engines are wonderful tools. Like all wonderful tools, they are not inherently benevolent. Unlike all wonderful tools, they are not only controlled by their user... Have you ever wondered that major search engines now know: where you live, what you search, what you post, where you buy, what you buy, where you advertise, what you read, what messages you send, what messages you receive, oh and what you have inside your pc. Your only slim advantage? that you know that they know. But they also know that you know that they know. And who is 'they' ? Just follow the money...
