The New York Times provides a great example of the use of online Q&A with their staff in their Talk to the Newsroom section. Readers are given the opportunity to ask a given staff member questions over a period of a few days and the staff member answers the questions as they come in (more or less).
It’s a good example of Newpapers/website editors interacting directly with their readership which in turn furthers the goal of transparency. The New York Times continues to try out new things and can be more cutting edge than many of their more recent web-only competition.
Have you seen other examples of this? Let me know in the comments.
