Just in from Microsoft Research, a new tool for ranking, sorting, and sharing search results called URank.  URank, a research prototype developed at Microsoft Research by Emre Kiciman, Shuo Chen, and  intern Konstantin Mertsalov, with some help apparently from Greg Linden  and others, allows you to move search results around to personalize your searches, collaborate with others to share searches, and much more.

You can watch a screencast of URank (“IE8 users, right-click and download the file and open in Windows Media Player”), learn more from the FAQ, check out the home page, or play around with URank yourself (feel free to add kip [at] LiveSide [dot] net as a friend).
