If you have ever been accused of being paranoid when it comes to electronic snooping you can stand up and scream your vindication now.
Just be prepared to see little hints come at you from everywhere you turn that indeed, "they" are listening and heard every word of it.
This is a pretty fascinating article from a guy who slowly became aware of just how pernicious and sneaky this constant monitoring of everything you think or do is now and then documents it.
I highly recommend you read the entire piece.
Then have those you love who have accused you of being paranoid go read it.
Tell them to prepare to apologise for doubting you.
All I can say is that this constant nagging, gut feeling that everything we do is being watched, stored and processed for future use against us is not just our imagination run wild anymore.
It's way worse than we imagined.
