Simon Jackman has some useful thoughts on the future of internet polling and why some of its critics don’t know what they’re talking about.
I’d also like to add that, as much as I rely on telephone sampling in my own research, I hate most of it in practice. Just yesterday, the phone rang and it was one of those robo-polls. I hung up, but I hated to even have to waste 5 seconds on the intrusion. I’m bothered by the asymmetry, that the survey wastes the time of the person who is being called while imposing a nearly zero cost on the pollster. Information pollution is what it is.
