Dear Danah Boyd,
In my opinion, the most salient lines of your entire article are: "Social technologies are undoing the private-by-default, public-through-effort norm that average people have when walking through this world. Participation in digital social media often means public-by-default, private-through-effort. Being watched is simply part and parcel with participating."
This is so true and so obvious in a world that is dominated by social media. By now, everyone has pretty much acknowledged that social media is not some fad to ride out like Pokemon or The Spice Girls (Yes, those were the first two examples I thought of). Every company is now embracing their online and social presence.
What has happened though, is a free-for-all of information sharing. It is almost useless to try to remain "private" if you want to be on any social media sight or even if you have friends on a social media sight. Just because you tweak your privacy settings to hide things like tagged pictures, the very same picture could be on your friend's profile with your name and info attached to it. Private-through-effort may not even be attainable right now, and no one seems to mind.
