SEARCH 2.0 - Update

Don't ask me why, but this is one of the most crowded categories;-). Search inspires many students & academics to come up with something new, most often just for play. My bet is that a few vertical and a few clustered search concepts stand a very tiny chance to work themselves out of Google's shadow. Only recently, I found a conceptual miracle called Fujiko - it's already there since 2005. Folksonomy-based search seems interesting too, but it's victim to a chicken or egg-dilemma: to make it really work you first need massive usage...
