Interesting point. But I believe the problem relies not in the sharing but in our perception of reality based on what others have shared. I understand that it's an inevitable consequence of the first but that has been the case for centuries. The new problem is that this misperceptions are now on a massive and unprecedented scale and our brain is constantly attacked by this misperceptions.
This is exactly right. The scope of social media is greater. It's a status show where your stuff isn't just in your living room but out there for you to “show off” to the world and compare it with others. This ultimately builds our story, our culture, that's when everybody believes a particular story and leads to the madness of crowds.
