Fact-checking for the masses

Now it's not just news anchors (and Jons Stewart) that can pull up a clip of file footage and catch somebody denying their own statements: the increasing prevalence of video cameras, combined with hosting and sharing sites like YouTube, is allowing regular folks to hold politicians accountable. Indeed, the rules are changing. Dare one hope that the result would be selection of better representatives, or will this just lead to more scripted events with prescreened audiences? (I'm going to hope for the former, clicking my heels along the way...)
