I was temporarily excited when I saw they had a link to their methodology. I always want to know how questions were phrased in surveys like this, since phrasing can affect the answers. Unfortunately the 3-page methodology doc didn't cover that. Like many such surveys, there's selection bias here in that it's people who have a land line and will agree to answer a survey about Facebook. This is going to bias toward people for whom something interesting has happened recently in their relationship to Facebook. Additional bias comes from the fact that the only participants invited were ones who previously agreed to answer a political survey.
