A lots of post about facebook recently. Why it will faill, why they should pay API developpers ... I even done one two days ago. Danah Boyd has written a piece called viewing American class divisions through Facebook and MySpace where she explained based on her observations that the gap between the two Social Networks could be a class division thing.
It's a must read because she points to something that could matter a lot. The post has drawned a huge amount of attention, a lot of criticism ... but a lot of folks (like me) do think she has put the finger on something real at the right moment. Bourdieu is quoted in the comments and there is a reason. Social Networks are about identity, identity is a social mirror. Social mirror is society and society is and always will be divided wether you form groups by political ideas, by respects of norms or even tastes. You can agree or not on Danah's terms (like subaltern) It doesn't change a thing. Enjoy the reading.
And let me dedramatize it with a joke about myspace and facebook from Casey Corbin:
