normative social influence

By: Jacob Taylor

I found this in my notes from my social psychology class:

Anonymity eliminates normative social influence.

So social networking sites are digitized networks graphs of normative social influence, encapsulated inside walled gardens(echo chambers). The data collected from the echoes is then used by the site and sold to other companies for advertising purposes. I can think of no more vile a thing.

Also, how do you reduce the SNR?
