Like you said people are `willingly` Instagram, Snapchat and Youtube and it's the information they choose to share. We can't blame people for being on social media. Because they expose what they want to show.
They can still be concerned google, facebook recording their every click, what grabbed their attention and precise information about their politicial views, or government surveillance.
First one is what you choose to share, another one is basically log of your activities even you don't know how much information it includes.
Absolutely no offense, I want to see the works of people who does this kind of comments all the time. I mean, I'm really curious what they are doing. I liked the the design of this website, but when I saw your comments it made sense, but still, I want to see what do you like or did.
