Kayak Buzz: Social Travel Search

Search service Kayak’s new “buzz” feature is interesting — in effect, a social search for travel. From the (currently) quarter-million searches done by Kayak users since Monday, you see (with obligatory Google Maps add-in) the best-priced travel from the location of your choice to Kayak’s 25 most popular travel cities. Here, for example, are the results for San Diego.
