Sorry for having to do the link like this but there seem to be technical issues with Weebly tonight and this seems to be a good work around for the moment.
Now I've talked before about interviewing your characters, which I find a really helpful way of getting to know them in depth before writing about them. But in your fictional world, who would do the interviewing of others? Who runs the media? What is the media in your setting? Are there certain people would never be interviewed (or it would be too dangerous to even try)? How do your people get their news? Does anyone ask questions on behalf of the layman? All things to think about which can add depth to your portrayal of your setting.
