One of the coolest YouTube mashups I've come across lately has to be TimeTube, a site that takes your topic and finds videos for it, chronologically, starting with the first and ending with the most recent.

For example, I typed in "American Idol" and got a video walk down Memory Lane....the first season, the worst auditions (and there were many), the winners, the losers, etc. Plus, TimeTube gives you more than one way to look at all these videos: timeline, list view, flipbook, and geolocation. Pretty darn cool.
