As I understand it Facebook began as a school-age-user-only site (that was the only way you could qualify to get on it) and only fairly recently opened up to the rest of the world because of financial pressures to compete with Myspace. So its funny to see Facebook users putting down Myspace as being for people who are immature. I found people my age notifying me they were now on Facebook also. The look of Facebook is decidedly humdrum in my opinion and there are a lot of aspects to it that are completely promoting conformity. It appears to welcome the mind set of people who are overly self-conscious and conformity prone.
I see all sorts of completely wild creativity on Myspace ( along with a lot of mess ) and practically nothing of that sort on Facebook. In fact, Facebook comes off being a really dull site in comparison. Paradoxically, for a cyberzone, I think Myspace strongly encourages individual expression and creativity within the limitations of its apps and technical paramters. I don't think that can as easily be said of Facebook.
It is interesting to see the cyberworld, because of variations in the characteristics of various sites, playing a part in defining basic differences in the psychologies of users and making it possible to break down the userworld into a very few starkly contrasting demographies.
