Google has my full search history, all my hangout chats, all my e-mails, and yet:
* On my Android, it keeps proposing ultra boring "stories to read" about soccer, wannabe celebrities and YouTube videos of stupid teenagers doing stupid things;
* With the sole exception of when the sponsored link is exactly the same as the first result, ad words in my search results have never ever been relevant or interesting in any way.
Facebook is supposed to know everything I like, yet it only shows me ads about stuff I dislike.
The same for Twitter and everything else.
They are supposed to know the inside of my heart and mind, but they have, till now, utterly failed to prove it.
So, do they know me and just pretend they don't for some strange reason, or do they actually know shit and just pretend they do so that they can sell to advertisers at a higher price?
