Facebook, a few more thoughts

Just being on facebook also gave me a couple more thoughts that I think are related to social psych. In case you guys don't know what I am talking about here is a link to the facebook page, while i am not advocating anyone joins www.facebook.com so what is facebook, well its kind of a little like myspace and is designed for people to be able to get back in contact with "lost" friends from uni or high school, was originally aimed for people in their mid to early fourties to "find" friends from their education.
However it has been dominated by people from the younger generation, and has been shown to be more than just a phase with it being used as not only a networking tool for old friends but also for the friends that you see everyday or even live with, particularly in the case of ressies. It can provide a place for groups to be formed such as the psych society for UC, in a non-confusing and friendly environment. It allows for people to essential blog, and comment on other people's walls, to upload photos or videos and to be 'nice' to people by buying them drinks or doing actions to them.
However in recent times there have been certain people complaining due to the vast amount of commands, showing that too much choice is a definate disadvantage but still facebook has outrun other similar sites with the number of people joined. It has also been praised for having a higher security and privacy level than other such sites but it still begs the question what level of security is needed on such sites
so to a few stats and interesting facts more than 43 million active users as of Setember 2007. The fastest growing demographic is people 25 and under – 85% of students attending 4-year
universities in the US are members of Facebook and was founded in 2004. The three main reasons for the popularity of facebook were the layout (look and feel + the amout of advertising)
the Applications (games) and the Exclusivism (you add only who you wish to). Facebook will remain to be cool as long as it keeps its sense of exclusivism and doesn’t sell out to advertising.
So i think why exploring facebook is important to social psychology are for the main reasons of privacy, of actual networking and why we need such technology as mobile phones as facebook, how they contribute or decrease our happiness and to what extent are the friends on facebook actually friends. How much mental and physical time should we be putting into such technology instead of face to face communication
Anyway enough of the ramble, interested in any thoughts you have on facebook, on the coolness, the privacy and the communication aspect, or anything else that may help the greater understanding of facebook and the way of the future :)
