There's a possible expectation of "accountability journalism" that includes fact-checking of interviewees and realtime challenge of misstatements. That also includes coverage of important but buried stories, wherein mainstream media is called to task for lack of coverage, etc.

The best recent example of this was the last episode of "The Daily Show," where accountability journalism was executed brilliantly. This could have a dramatic effect on American politics, and out here, we feel we sure need it.
