I would be on the lookout for some sampling error here. I found this survey through HN, which I assume isn't exactly populated by the poor and disenfranchised. how else are respondents being driven to the survey?
also, the answer is yes. Myspace is totally for the poors.
Yes I totally agree about the sample error. I'm trying to make up for it by inviting people on reddit, small forums, Google Wave and other sources that I have access to.
But I totally expect a sampling skew because I am strongly rooted in the "Facebook" community and will find it hard to reach the MySpace group because of this "digital divide". I'm also planning to balance things out with real world survey attempts, talking to people on the street.
also, the answer is yes. Myspace is totally for the poors.
