Danah Boyd has written an article called "Viewing American class divisions through Facebook and MySpace". His struggle to talk about class division in America and attempt to use social networking sites as an example is fascinating.
Though tangential to the article as a whole, I thought this bit about young soldiers changing attitudes to war was amazing (emphasis in quote is mine):
A month ago, the military banned MySpace but not Facebook. This was a very interesting move because the division in the military reflects the division in high schools. Soldiers are on MySpace; officers are on Facebook. Facebook is extremely popular in the military, but it's not the SNS of choice for 18-year old soldiers, a group that is primarily from poorer, less educated communities. They are using MySpace. The officers, many of whom have already received college training, are using Facebook. The military ban appears to replicate the class divisions that exist throughout the military. I can't help but wonder if the reason for this goes beyond the purported concerns that those in the military are leaking information or spending too much time online or soaking up too much bandwidth with their MySpace usage.
MySpace is the primary way that young soldiers communicate with their peers. When I first started tracking soldiers' MySpace profiles, I had to take a long deep breath. Many of them were extremely pro-war, pro-guns, anti-Arab, anti-Muslim, pro-killing, and xenophobic as hell. Over the last year, I've watched more and more profiles emerge from soldiers who aren't quite sure what they are doing in Iraq. I don't have the data to confirm whether or not a significant shift has occurred but it was one of those observations that just made me think. And then the ban happened. I can't help but wonder if part of the goal is to cut off communication between current soldiers and the group that the military hopes to recruit. Many young soldiers' profiles aren't public so it's not about making a bad public impression. That said, young soldiers tend to have reasonably large networks because they tend to accept friend requests of anyone that they knew back home which means that they're connecting to almost everyone from their high school. Many of these familiar strangers write comments supporting them. But what happens if the soldiers start to question why they're in Iraq? And if this is witnessed by high school students from working class communities who the Army intends to recruit?
