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.
