Are you saying that the nature of friendship some sort of absolute that is unaffected by changes in the structure of peoples' day? Like email, facebook is a new medium for friendship, with a multitude of new methods of communication. For example, the like button is a new way to acknowledge in a highly neutral manner. I "like" the cat picture, I also "like" how someone said that they have cancer. Mechanisms like "like" are fundamentally changing the nature of the relationships established and maintained, and it is having an effect outside of that new medium.
Success and power have also changed. Before twitter and facebook in the late 90s and early 00s, do you think that the centralized mass media or the widespread use of email made people successful or famous in the same way? The brain structures are the same, but the culture has changed along with the environment.
Perhaps she wants us to understand that because the same can be said for architecture. The effect of architecture on daily life is far greater IMO. Modernist and international style buildings completely changed what happened at the street level and wiped out entire societies that existed. Only now are mixed use buildings attempting to restore street-level normalcy, except that it will be different. This is because, like facebook that improves upon email, the medium is different than it was in traditional pre-modernist architecture.
No, it really, really, has not.
> But more than that, Facebook, along with all the start-up successes of Silicon Valley, has also disrupted paradigms of success and power.
Huh, seriously? Who makes this stuff up?! Maybe the author should get out of SV every once in a while to see that in the rest of the world, the concepts of "success" and "power" have not changed in the last 10 years.
