I just read danah boyd's articulate set of observations on the apparent socioeconomic split between the young users of MySpace and Facebook. If you're curious about this too, you should definitely read the essay, but this may be the summarizing excerpt:

The goodie two shoes, jocks, athletes, or other "good" kids are now going to Facebook. These kids tend to come from families who emphasize education and going to college. They are part of what we'd call hegemonic society. They are primarily white, but not exclusively. They are in honors classes, looking forward to the prom, and live in a world dictated by after school activities.

MySpace is still home for Latino/Hispanic teens, immigrant teens, "burnouts," "alternative kids," "art fags," punks, emos, goths, gangstas, queer kids, and other kids who didn't play into the dominant high school popularity paradigm. These are kids whose parents didn't go to college, who are expected to get a job when they finish high school. These are the teens who plan to go into the military immediately after schools. Teens who are really into music or in a band are also on MySpace. MySpace has most of the kids who are socially ostracized at school because they are geeks, freaks, or queers.

...of course, this can read like broad generalization without allowing yourself context. So don't go yapping your mouth without reading the whole thing.

I certainly approach this subject with my own biases that aren't secret at all. In fact, it's plastered on my MySpace profile. Primarily from the perspective of someone who has worked on the Web for the past 8 years (yet also as a John Q. Public user), I loathe MySpace and wish I could take all my friends with me to Facebook. (Fwiw, I used to love Friendster too, and I thought Orkut was decent). To my earlier point about the above quote providing only an illustrative takeaway, I'd never classify myself—not now and certainly not when I was a teen—as hegemonic. But I digress, as the article certainly wasn't about me at all. I often forget I haven't been a teen for a long while. Perhaps, if I'm so inspired by how uninspiring MySpace is, I'll write some more on how MySpace is not....well, my space.

So now, in addition to being a web usability and aesthetic train wreck, MySpace can now come with a social stigma too! Just as one's realization of being perceived as underclass can manifest into a "Fuck the world, and I know you're looking at me!" sentiment offline, I wonder how the MySpace kids would react if presented with this information. How would they metaphorically add more piercings or let their pants sag lower?

Although Facebook was love upon account activation for me (so was tribe.net, by the way) and MySpace the opposite, I continue to maintain accounts on both (Tribe too). After all, it's the Network Effect at work here, and I'm interested in keeping touch with all my people, not just my informed friends, those who were fortunate enough to leap across the digital divide sooner than others.
