I received the following email today: I am preparing a thesis … I need to conduct the widest possible poll, and it occurred to me that perhaps you could guide me toward an internet-based way in which this can be done easily. I have a ten-question questionnaire prepared, that I wish to have an random sample of the population respond to. I have no budget for this, so I hope you can suggest a way in which a good number of responses can be harvested using blogs or sites you may be aware …
