UIE Brain Sparks has a pointer to a series by Leisa Reichelt about "accepting the unscientific qualities of qualitative research, and using qualitative research as a flexible way to gather rich and insightful information about your intended audience." They provide a brief conversational apologia for qualitative research, which probably won't convince skeptics but which are interesting anyway.
Presumably this has something to do with the way the Democratic YouTube debate went. Too bad: The questioning is less controlled, and I suppose the candidates think it's beneath their dignity to be asked questions by animated snowmen and so forth, but the YouTube debate was useful in that it gave actual non-journalists and non-politicians the chance to ask questions. I don't think this will play well. The only Republican candidates who have signed on are John McCain, who has nothing to lose, and Ron Paul, who -- in addition to having nothing to lose -- has shown strong willingness to engage with distributed media.
