i think all of this comics (exception made for the last one) can be applied to both fb and myspace, so i don't see why to bicker, since elvina has myspace too, as a lot of us.
i have opened my fb account really late, not for any ethic question, but because fb and myspace are more or less the same old story, but simply with different layouts/settings, and i didn't want to lose too much time following both of them, having the same friends on both and discussing the same things on both.
but myspace is as superficial as fb, so i don't see much difference.
then myspace exploded and fb seemed the only option for me to keep in touch with some people who live far from here. but at the beginning my choice between fb and myspace was only motivated by a more freedom you have with myspace in customizing the page, adding a nice background picture, some more profile photos, video and songs, i felt it to be more personal....
