One problem with a lot of video on news web sites is a lack of searchability. Many users simply don’t want to spend their time watching a clip all the way through to find a particular segment that’s pertinent. MSNBC’s interactive video timeline is one answer, used in this case to help viewers through the series of McCain v Obama presidential debates. It isolates key words and phrases used by both candidates and allows you to fast-forward to where they appear in the debate, so if you have a particular interest in health care or Iraq, say, you can easily identify the right segments.
