Only to a point, with the absolute shite that the average idiot posts on social media in a day you realise that not all information is useful, not all data is equal, you have to sort the wheat from the chaff or you do end up with true information overload. The reality is people freely and willingly give the likes of Google, Apple, Twitter, PayPal and Facebook more useful info than the "Man" could ever hope of collecting as that collection of data is targeted.
The reality is that unless you say you want to "Scalp President Trump" (that's easy, throw a stick and his hair will chase it) or that you will "Sneak a SNUKE up Shillary's snatch" then, frankly, anything they MIGHT have on you, yourself, is what they use to cure insomnia, it is of no value, your midget porn fetish does not interest them.
