Most interestingly, from my personal observations, US users under the age of 18 prefer the "uncontrolled" nature of Myspace versus the structured "social institution" feel of Facebook. Also, as Facebook's users become more familiar with its workings (social, not technical), it becomes quite apparent that there are limitations to having all relationships equal. This is truly where Facebook fails. I have friends, I have a best friend, I have acquaintances (both business and social), and I have people I don't like, I may have some enemies, too. But in the realm of Facebook, all these people are my friends, and I have no way to differentiate that within the Facebook platform. I do not believe it is the UI that is the problem, but the underlying architecture of it's "social functionality".
