I'm glad social media didn't exist when i was younger, I sure as hell wouldn't want some of the things that I've said and done following me throughout my lifetime. What I don't understand is how the current generation fails to understand this simple concept. Employers are using FB as a background investigation tool and people are becoming otherwise unemployable because of the crap they choose to allow the entire civilized world to see lol.
How about when your surfing and a random thought comes into your mind, lets say, about hostess cupcakes, and then the next time you are on the internet you see ads for hostess making loving cupcakes! wtf is that about?
Everyone needs to remember that when you use google, fb, etc.... YOU are the product. If you don't want them to use your information for profit then go to the library for information.
