I used the word branding here because people change their behavior based on what how people view them. Of course, I'm not saying that everyone is shallow and whoring themselves because somebody said something

My point is that, you have more media that before, and that this media is becoming deeper than before.

Take an example: your photos are not just a piece of paper anymore. There's a whole new problematic now that they're more social: which photos will you share? who will see them? These kinds of decisions are becoming more and more normal, and they affect the way you behave.

I agree it's a lot more complicated than before. Of course people don't / won't have to be super social beings all the time. But as content becomes more like this, and people become more like this, there will be more and more peer pressure to do so.

Just look at how in only 2 years, everyone joined Facebook, and is almost -expected- to maintain "relations" with people there.

How 'bout the people who a) don't care to brand themselves or b) are not able to?

In any case, it all sounds like a lot of work. And I'm not sure it's a necessity to us all.
